Left 4 Dead – The Achievements
If you need help obtaining achievements, or simply want to know the ‘rules’ involved when attempting one, everything you want to know is right here in this comprehensive guide!

Campaign Mode

   DEAD STOP - Punch a Hunter as he is pouncing.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
When you see and hear the hunter pouncing, look upwards and melee him whilst in the air.

  DRAG AND DROP – Rescue a Survivor from a Smoker's tongue before he takes damage.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Melee the survivor before they get completely pulled up to the smoker or shoot the smoker before the survivor reaches him. Bot participation may hinder this achievement as they will also try to rescue survivors.

  CR0WND - Kill a Witch with a single headshot.
How Best Achieved;
Level: Any
Difficulty: Easy
Bots: No
One of the most feared achievements’ but actually relatively simple. Using an auto shot gun, you must run up to a Witch and shoot her (auto shotgun works best) at point-blank range in the face before she can attack you. If done right, the Witch will die instantly, getting you the achievement and ridding the game world of one more Witch. This might take a few attempts so keep trying. It can also be done with the pump shot gun but is much more difficult. You will also get Witch Hunter if no survivors take any damage.

UNTOUCHABLES - No Survivors take damage after contacting the rescue vehicle.
How Best Achieved;
Level: Dead Air, Runway Finale
Difficulty: Easy
Bots: No
You can simply just play the finale of any campaign no need to do the entire campaign. Best done in Dead Air, go all the way to the left, behind the truck, by the fence in the corner. Shoot all zombies quickly with pistols and use shotgun for tanks. Run towards tanks light him up with a molotov and unload auto shotgun into him whilst running backwards before he hits anyone. When the second tank dies be careful! There will most likely be a smoker or hunter (sometimes you'll get both) by the escape plane. Try to shoot them quickly. Run to the back of the plane protecting each other as much as possible.  
Untouchables can also be achieved in Death Toll.  Use the rock to the far right of the map, past the dock. Jump up onto the rock (can be difficult), get everyone up there and you should be fine. Smokers can drag you off so be careful. Zombies can only climb from in front and tank will throw rocks. When the second tank has died, WATCH OUT FOR THE HUNTER ON THE DOCK!!!! He’s almost always there, shoot him quickly go up to the stairs on the dock and wait for the boat.

  BLIND LUCK - You or another Survivor take no damage after being vomited on by a Boomer.
How Best Achieved;

Bots: Optional
Protect or be protected after being vomited on by a boomer. The player can hide in a closet until the effect has worn off.

  AKIMBO ASSASSIN - Survive an entire campaign using only pistols.
How Best Achieved;
Level: Any
Difficulty: Easy
Bots: Optional
If your team mates do not protect you, you’ll be in for a long night…
No primary weapons allowed. No mounted weapons allowed. This counts for bashing with a primary weapon as well, but not for bashing with the pistols. This is a single player achievement, so feel free to have your team mates use regular weapons while you use your pistols. DO NOT carry a primary weapon throughout the entire campaign. Picking up a primary weapon will result in failure. Also, do not melee whilst your health kit or pills are selected as this will also result in a failed achievement.
 

  FIELD MEDIC - Heal 25 Survivors with a first aid kit.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Too bad buddy! Pull out your health kit and use it to heal a survivor! Go On! You CAN do it!

  HELPING HAND - Revive 50 incapacitated Survivors.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Forget that your own health is fading fast, forget the screaming horde on its way to wreak destruction, forget the comfort that is just behind that safe room door and rescue 50 incapped survivors!
 

  HERO CLOSET - Rescue a Survivor trapped in a closet.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional

  TONGUE TWISTER - Kill a Smoker who has grabbed you with his tongue.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Use an auto shot gun or m16. When the smoker grabs you spray at him quickly before he drags you too far and you’re unable to shoot him anymore. Best done if the smoker is relatively close to you. 1-2 hits from auto shotgun will usually kill him.
 

  NO SMOKING SECTION - Kill 10 Smokers as they are pulling helpless Survivors.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Simply melee’ing a survivor from the smokers tongue will not get the achievement. Ensure 10 smokers feel the wrath of your auto shotgun to obtain No Smoking Section. Then sit back, relax and enjoy a cigar!

  101 CREMATIONS - Set 101 Infected on fire.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Throw a molotov towards a large horde, picking up a pipe bomb and tossing it into the flames will attract more of the horde guaranteeing you zombie toast!

  DO NOT DISTURB - Sneak past all Witches in a campaign without disturbing one.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Flash Lights off and sneak! Bot participation may make this achievement difficult to obtain. Bots love to disturb witches!
 

  MAN VS TANK - Single-handedly kill a Tank.
How Best Achieved;
Level: Any
Difficulty: Easy
Bots: No
You will need 4 people as attempting this with Bots will result in a fail. On ‘Easy’ the Tank is easier to kill. 
Throw a Molotov at the tank , light him up and watch him burn!  Shoot him once or twice and then run away (everyone). Stay away from the tank until he dies and you’ll get the achievement immediately. (If no one takes damage from the tank you will also get Tank Busters)
 

  TANKBUSTERS - Kill a Tank without it dealing any damage to a Survivor.
How Best Achieved;
Level: No Mercy, The Subway
Difficulty: Any
Bots: Optional
Easiest way to do this is on No mercy the subway. Sometimes a tank will spawn upstairs by the subway, throw a molotov at him and run you have plenty of room so should be easy to avoid him. He will eventually die from the molotov so just keep running away from him.
 

  SAFETY FIRST - Play an entire campaign with no Survivors taking friendly fire damage.
How Best Achieved;
Level: No Mercy
Difficulty: Easy
Bots: Absolutely Not!
This is one of the hardest achievements. DO NOT ATTEMPT THIS WITH BOTS!
From personal experience attempt No Mercy, on easy. Friendly Fire damage includes walking into Molotov fires, pipe bomb damage, and the regular shot-in-the-back kind of fire.  Melee only when close to team mates. This will take patience and practice! Just for the hell of it, try attempting this achievement on Expert, where a single shot from almost any weapon will instantly incap a survivor!  Have fun!

  NO-ONE LEFT BEHIND - Beat a campaign with all 4 Survivors.
How Best Achieved;
Level: No Mercy
Difficulty: Easy
Bots: Optional
Easy, just protect each other and make sure you all get on the rescue vehicle. Best obtained on No Mercy as it’s hard for you to get knocked down while on the helipad, also its one of the quickest rescue vehicles to arrive.
 

  UNBREAKABLE - Finish a campaign without ever using a first aid kit on yourself.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: No
Better hope you have a good team that knows how to protect. Survive an entire campaign without using a health kit. So do not heal yourself or allow others to heal you. You CAN use pills!!! This is best attempted without bots as they WILL heal you if your health falls below 50. If a bot does try to heal you, pulling out your health kit (don’t use it) will prevent them from healing you. Try to protect yourself as much as possible and hope your team can protect each other.
 

  WITCH HUNTER - Kill a Witch without any Survivor taking damage from her.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Run up to the witch with auto shotgun and unload a clip into her. If done correctly you'll kill her before she has time to be startled. If you shoot her in the head you can also get Cr0wnd.
 

  RED MIST - Kill 1000 Infected with a mounted machine gun.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
A thousand infected with a mounted machine gun? Bring it on!
 

  PYROTECHNICIAN - Blow up 20 Infected in a single explosion.
How Best Achieved;
Level: No Mercy, The Subway
Difficulty: Any
Bots: Optional
After you go up stairs where the subway trains are there is usually a large horde. Throw a pipe bomb which most of the time can be found downstairs in the booths by the tolls.
 

  ZOMBIE GENOCIDEST - Kill 53,595 Infected.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
The achievement will be obtained over time. It should take around approximately an average of 107 hours of gameplay. The Gatlin Gun will notch up the kills, so go for it! Hope you have enough coffee or tea depending which is your favourite, to stay awake that long! Both Special and Common Infected count towards the achievement.
 

  DEAD GIVEAWAY - Heal a fellow Survivor when your own health is below 10.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Bite your tongue and go for it and just hope you have another team mate standing by to heal you too! 
 

  GROUND COVER - Save another Survivor from a Special Infected while on the ground.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
This is best obtained if a hunter pounces a team mate next to you while you’re incapped. Shoot the hunter in the head and you’re all done.
 

  CLEAN KILL - Shove a Boomer and then kill him without him splashing on anyone.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Melee a boomer then run backwards. The boomer will wobble backwards too, so when you think you’re far enough not to get splashed, shoot him. This is best achieved while he’s still wobbling backwards.
 

  STAND TALL - Survive a campaign without being incapacitated.
How Best Achieved;
Level: No Mercy
Difficulty: Easy
Bots: Optional
Not the hardest achievement but not the easiest either. Best way to do this is on Easy, No Mercy with 4 people.
Have friends protect you but watch your back closely. Moving through the map quickly can be easier than taking your time as less hordes and special infected will spawn. Be careful not to get close to the tank and avoid witch at ALL COSTS! As just 1 hit will incap you.
 

  BACK 2 HELP - Leave a safe room to save an incapped teammate and bring them back safely.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Just when you thought you were safe..... back  you must go to save a team mate!
 

  ZOMBICIDAL MANIAC - Survive any campaign on Expert.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Pick a campaign and follow the same rules as for "What Are You Trying To Prove?"
 

  WHAT ARE YOU TRYING TO PROVE? - Survive all campaigns on Expert.
How Best Achieved;
Level: All
Difficulty: Expert
Bots: Optional (best without)
If you’re playing with a crap team you are in for a longgggggggggggggggggg night.
The key is to protect each other, getting special infected off each other as quickly as possible. Light tanks on fire with Molotov’s and run. You must play from the beginning of the campaign and make it to the rescue vehicle.

 

No Mercy Finale:
Do this on the back stairs of the room where the radio is.  Have 2 survivors upstairs, 2 downstairs. Standing in front of each other, the back player stands using shot gun, the player in front crouches and melees. Stock up on ammo and health between hordes. All players use shot guns for tanks. 

Death Toll Finale:
Go towards the dock where the rescue vehicle comes. Continue passed the dock to the far left of the map. Jump up on to the rock in the water by the mountain side, (this will take some practice). Use dual pistols for the zombies and unload into the tank with auto shotgun. Remain on the rock until you have killed the 2nd tank then make a run for the dock and await the arrival of the boat (rescue vehicle). There will be a hunter waiting as you approach the dock to be aware. A final horde will spawn as the rescue vehicle arrives, throwing a molotov or pipe bomb will keep them at bay until you can jump on the boat.

Dead Air Finale:
Do this in the far back corner behind the pump trucks against the fence. Stash Gas tanks and propane in the corner and toss out when needed. Shoot hordes with pistols and use auto shotgun for tanks. Run up to the tank and start shooting him as you run backwards to the fence. This is most effective if 2 or more players work together.
It can also be done at the back of the hill by the escape plane. If done on the hill, circle around the plane when shooting the tank.  This technique is also good for avoiding the rocks that the tank bombards you with. 

Blood Harvest Finale:
This can be achieved on the second floor of the large red barn (the one with ammo on the second floor).
All four players stay in the corner against the roof behind the hay bails. Use shotguns the entire time as ammo is close and unleash into the hordes. Hunters can come from the hole in the roof but smokers and boomers will only come up the ladder. When tank comes use a Molotov to set him on fire. Use pipe bombs to distract and kill hordes. Go out of the hole in the roof and unload into him quickly. Be careful for smokers that might drag you down. If the Tank gets up jump out either the window or the hole in the roof which ever is easier, and where he wouldn’t be able to get to you. Window works best as he can’t climb up that way. If he still hasn’t died circle around the Farm House shooting him when you can and avoid when he throws rocks. Try and stay as a team. All finales are best achieved when the team stick together.
 

  NOTHING SPECIAL - Survive a campaign with no Survivors taking damage from Special Infected.
How Best Achieved;
Level: Dead Air
Difficulty: Easy
Bots: Optional
THIS IS BY FAR THE HARDEST ACHIEVEMENT and requires no survivors to take any damage from any Special Infected during an entire campaign. There is also a less known rule here: damage done to a survivor by zombies attracted by Boomer bile counts as damage from a Special Infected. However, Smokers and Hunters do not damage the player initially, so knock them off before the achievement is ruined. Avoid witches completely and apply extra caution to tanks.
Best way to do this is to throw away your tent pegs, put your skates on and run through the entire campaign (we did it on dead air). Alternate between melee and attack as you come across small hordes but keep running! Do Not Stop! When you run fairly quickly through the map it can result in less zombies spawning and less Special infected spawning.
We found it easier with 1 bot (seems to work more often when there is a bot) Just hope that he doesn’t get attacked by Special Infected. Also, be careful with tanks they might sometimes spawn after 1 person has passed (has happened with me as I flew past and he then spawned in front  of my 2 team mates.)
For the finale follow the "What are you trying to prove?" finale tips and you should be ok in dead air.
 

  BURN THE WITCH - Light a Witch with a Molotov.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Simply toss a molotov at the witch. As long as she’s on fire you'll get the achievement, you do not have to kill her with it.
 

  TOWERING INFERNO -  Light a Tank with a Molotov.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Throw a Molotov at the tank and set him on fire. This can also be done if you follow the Man Vs Tank part of this guide.

SPINAL TAP - Kill an Infected with a single blow from behind.
How Best Achieved;
Level: No Mercy, The Apartments
Difficulty: Easy
Bots: Optional
Spawn and jump down into the room via the glass skylight and melee a zombie directly in the back.

  STOMACH UPSET - All Survivors complete a campaign without being vomited on.
How Best Achieved;
Level: No Mercy
Difficulty: Easy
Bots: Optional
Another extremely hard achievement, the entire team must avoid being covered in Boomer vomit for the entire campaign. Whilst the achievement says you must avoid only the vomit, it also includes the bile flung by a Boomer explosion as well.
This is best done with all players running through the map the entire time. Bots are useful at pushing boomers back and shooting them. When you hear a boomer, the best way to kill him is either; melee him, run backwards and shoot him, or to shoot him through walls.
On No Mercy in the sewers, a boomer almost always waits out side one of the tunnels. Go to the left and come out on the other side and shoot him. This is a relatively hard achievement to obtain. 
 

  BRAIN SALAD - Make 100 headshot kills.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
Steady, Aim, Fire! You’ll do this surprisingly quicker than you thought… if not…just keep trying!
 

  JUMP SHOT - Headshot a Hunter while he's leaping.
How Best Achieved;
Level: Any
Difficulty: Any
Bots: Optional
The best weapon from personal experience is auto shotgun or m16. When hunter pounces and is in the air, shoot, aim and hope it’ a head shot!

  MERCY KILLER - Survive the No Mercy campaign.
How Best Achieved;
Level: No Mercy
Difficulty: Easy
Bots: Optional
Having obtained this 'the hard way' then playing this campaign over and over again, we found this achievement easily obtained if you get through the campaign as quickly as possible. Keep running, melee and shoot hordes and special infected on the way. Make your dash from safe room to safe room and this entire campaign can be completed in under 20 minutes!
Seriously, just stay alive until you get to that god damn safe room!  Heal, or carry a spare kit, ammo up and off you go again. Follow ‘What are you trying to prove’ tactics for finale.
 

  TOLL COLLECTOR - Survive the Death Toll campaign
How Best Achieved;
Level: Death Toll
Difficulty: Easy
Bots: Optional
The start of this campaign is quite difficult but we found it gets easier as you progress through the game. Always try to replenish Molotov’s and pipe bombs when used. Make good use of gas tanks, propane or oxygen tanks. You can even carry them with you for those difficult times ahead. As with the other campaign achievements, do it on 'easy' and 'run' through the campaign, melee and shoot hordes and special infected as you dash from safe room to safe room. Follow ‘What are you trying to prove’ tactics for finale

  DEAD BARON - Survive the Dead Air campaign.
How Best Achieved;
Level: Dead Air
Difficulty: Easy
Bots: Optional
As with all campaign achievements, we first did them the hard way. Once the achievement was obtained we then started to see how they could be best obtained. Surviving an entire campaign can be quite difficult. We found the easiest way to complete this achievement was on Easy. Get through the entire campaign as quickly as possible. Running from safe room to safe room, melee'ing and shooting hordes and special infected. Again , completing the entire campaign can be achieved in approximately 20 minutes!
Follow ‘What are you trying to prove’ tactics for finale 

  GRIM REAPER - Survive the Blood Harvest campaign.
How Best Achieved;
Level: Blood Harvest
Difficulty: Easy
Bots: Optional
Again, this achievement can be obtained in approximately 20 minutes! Just keep running, melee and shoot hordes and special infected on your mad dash from safe room to safe room!
Follow ‘What are you trying to prove’ tactics for finale  

 

Versus Mode
 

  BARF BAGGED - Cover four Survivors with Boomer bile at once.
How Best Achieved;
The best way to do this is to wait around a corner, try to catch survivors off guard
and hope that they come in a tight group. All four players must be vomited on at the same time. Exploding will not count toward the achievement.

  BIG DRAG - Drag a Survivor 100 feet with your tongue as a Smoker.
How Best Achieved;
Be as far away as you can possible be (when the cross hair for the tongue is still red but one more step and it isn’t).
This is best achieved if you spawn behind the survivors just before a trigger event like No Mercy, The Subway or the Elevator in the Hospital.
 

  CHAIN SMOKER - Constrict two Survivors on one life as a Smoker.
How Best Achieved;
Best achieved on No Mercy, The Subway, upstairs where the Gatling gun is. Stay upstairs on the second floor and hide until you can grab one person with your tongue. Usually, the player will get melee’d off (rescued) so hide and wait until you can constrict again. Try to grab the second survivor when they are near to the stairs that lead up to the second floor.

  DOUBLE JUMP - Pounce two different Survivors on one life as a Hunter.
How Best Achieved;
This will take several attempts.  You need to pounce someone, kill them, then pounce someone else but it is difficult to do that. It is easier if you pounce someone and if a survivor melees you off, simply get back into pounce mode and pounce the person that melee’d you. Also, take the opportunity to double jump when a boomer biles on the survivors and are distracted by the horde or better yet a tank.
 

  ALL 4 DEAD - Kill all four Survivors on one life as a Tank.
How Best Achieved;
The easiest way is No Mercy, The Hospital and hope you become the tank near the end of the level by the safe room. Either incap all survivors on the ground or knock them off the edge of the roof.

  DEAD WRECKENING - Dole out 5000 total Survivor damage as a Special Infected.
How Best Achieved;
Grab a nice drink you'll be here for a while. Perseverance is the key. Keep at it and the damage will soon add up.
 

  LAMB 2 SLAUGHTER - As an Infected, incap a Survivor who has entered and left a safe room.
How Best Achieved;
This is best achieved as a smoker. Try to drag a low health survivor out of the safe room and incap them. This can be somewhat difficult to obtain. It is also possible to do as a hunter the survivor will have to first enter and leave the safe room.

  OUTBREAK - Catch a rare strain of infection, then pass it on to someone else
How Best Achieved;
This achievement has been discussed more than any other achievement in Left 4 Dead due to its wording.
Basically, Outbreak involves you catching a rare strain of infection from ‘Boomer vomit’ and then passing it on to another survivor.
The virus can only be gotten from someone playing a boomer who has already achieved Outbreak.
Once vomited on, quickly pass on the infection to a survivor who is not covered in boomer vomit by touching or meleeing them. 

 

Survival Mode
 

  LAST STAND – Complete one round of Survival on The Last Stand
How Best Achieved;

The Generator Room:
Before calling the horde throw the 2 gas tanks up to the second floor and make sure all players have Molotov’s. Start in front of the shutters that lead to the upstairs. When the door opens go upstairs and move 3 gas tanks into the corner between the boxes.  Throw the other by the top of the stairs, and shoot it when the horde comes. Toss other gas tanks when required. Repeat until all the gas tanks have been used, then use your Molotov’s. There are also 4 pipe bombs in the same corner. All four players stay in the corner. Use pistols for hordes and auto shotgun for tanks. EVERYONE should have auto shotgun. Tank will almost always climb up  the left side so just shoot him as he climbs and finish him off quickly. Said to be one of the hardest Survival Mode levels. Quite difficult to achieve Gold.
Our Best Time to Date: 14m 20s

 

The Gas Station:
All get on the lift and call in the horde, run across the roof into the room on the other side, go down the hole in the floor and everyone jump on top of the tables in the corner. This is best done with all 4 players using auto shotguns.  Be careful for smokers as they may drag you out the window. Use pistols for hordes and auto shotgun for tanks. Quite difficult to achieve Gold.
Our Best Time to Date:  11m 39s
 

The Hospital:
Start in the cubicle with the bed right across from the ammo, call the elevator. After about 2 or 3 minutes the double doors at the end of the hall (on the right) should open. Grab some ammo and run into the room where the doors have opened. It’s best that all 4 players are crouched in front of the door. Use auto shotguns the entire time making sure to make ammo/health pack runs when possible. Not too difficult to achieve Gold.
Our Best Time to Date: 14m 30s 

The Rooftop:
Stay in the room downstairs where the radio is. Use shotguns the entire time making ammo/health pack runs upstairs when possible. Each person should cover a general area of the room. Quite difficult to achieve Gold.
Our Best Time to Date:  22m 59s
 

The Drains:
Get the pipe bombs/Molotov’s on the table by health packs. Go up the ladder by the tube next to where you spawned. Go through to the other side and cover the tube. Have 3 people covering the pipe as 80% of the infected will come this way and the other person covering from the left and right as infected sometimes spawn behind them. Use pistols for hordes and auto shotgun for tanks. We found that attempting ammo runs on this level would ultimately end badly. Quite difficult to achieve Gold.
Our Best Time to Date: 12m 18s
 

The Church:
Stay in side the church in the corner closest to the room with the health kits. Use auto shotguns the entire time make ammo runs (as a team) when needed and quickly return. Be careful for the smokers that like the window across from that corner. Stay together and keep shooting!!!  Very difficult to achieve Gold.
Our Best Time to Date: 11m 32s
 

The Street:
Everyone should have auto shotguns. Run backwards from where you spawn against the fence all the way at the end of the street. Use pistols for hordes and auto shotguns for tanks. Have 3 people cover in front and 1 person covering the fence area as some zombies do try to climb over. You can use pistols for hordes and auto shotguns for tanks. It is easy to make ammo runs as well.  Not too difficult to achieve Gold.
Our Best Time to Date: 11m 40s
 

The Boat House:
Best place to do this would be exactly where you spawn but in the corner closest to the dock. Gather all the gas tanks place them in the corner tossing them and setting them on fire when needed. Since you’re close to ammo and guns, and health kits this is a great spot. You can use M16 for hordes and switch to auto shotguns for tanks. Tanks will most of the time come from the second floor of the house. Can be very difficult if the tank doesn’t die fast enough or if players start getting caught by hunters/smokers. Quite difficult to achieve Gold.
Update: It is possible to get on the roof of the building where all the picnic tables are. What you need to do is throw a propane tank at one of the picnic tables to first move it to the front of the building. Then move it round to the side until it starts to incline a small hill. Use the table to jump onto the roof.
Our Best Time to Date: 34m 10s
 

The Crane:
Arguably the hardest achievement.
This is best done on the roof top with the ammo, guns and health kits. Everyone should have m16 most of the time and switch to shotgun for tanks. 1 person should cover the roof to the right from smokers!!!! (Important job).
The other 3 players cover the windows in front of them. As soon as the crane is started, most infected will spawn from the windows. The Tank will often come from the windows too, so just unload clip after clip into him. Sometimes he might spawn on the roof on the right. The person watching the right for smokers should warn that the tank has spawned there. If he does, he'll fall down and climb up the building via the left side. So get auto shotguns and unleash on him when he gets back up. Very difficult to achieve Gold.
Our Best Time to Date: 24m 18s
 

The Construction Site:
Extremely difficult. Gather all the gas tanks and put them on the stairs opposite to where you start the event. Everyone should have Molotov’s and shotguns. Stay on the stairs, throwing gas tanks over the railing and setting them on fire when needed .When you’re out of gas tanks use your Molotov’s, making them last as long as possible. When tanks come open fire with auto shotgun as he climbs the railings of the stairs. 3 people watch the side and 1 cover the front with pistols. Multiple smokers spawn on the second floor and will drag from the window. Very difficult to achieve Gold.

The Terminal:
Stay against the fence by the desk with the Molotov’s and pipe bombs, where the van would normally crash through. Use auto shotguns the entire time running for ammo whenever possible. Save grenades for as long as possible. Hordes will only spawn from in front of you. When tank comes, as usual unload your auto shot gun into him. Not too difficult to achieve Gold.
Our Best Time to Date: 16m 47s
 

The Runway:
Use auto shotguns for tanks and pistols for hordes. Stay either on the hill behind the plane or all the way in the far left corner of the map against the fence (as explained in “What are you trying to prove?”). The best place would be against the fence as they mainly come from in front of you and rarely over the fence. Quite difficult to achieve Gold.
Our Best Time to Date: 13m 58s
 

The Lighthouse:
Another extremely hard level! Best done with 3 auto shot guns and 1 sniper (yes a sniper! finally the most useless gun in the game has a purpose).
Where you start this event, there are 2 big boilers against the back wall. Jump on top of them via the dumpster. Two players take up positions in the middle and 2 in the corner. Players stand in front of each other with the front player crouched. To prevent being bumped off the boiler by a team mate, hold your ‘backwards’ key. The snipers only real job is to protect the other players from smokers and hunters. Both the front and back walls are broken with hordes so cover both sides. Having all 3 players use the auto shot gun on the tank will usually kill him before he climbs the boilers. Point blank range will do more damage, so hold fire until he is in the boiler room.
Very difficult to achieve Gold.
Our Best Time to Date: 13m 39s
 

The Warehouse:
With all playing taking auto shot guns,  open the door that starts this event and keep running! Run up the stairs on the right follow the path all the way to the end and you’ll reach a set of stairs with a shelf on the right. Stand on top of the oxygen tanks on the floor you’ll be able to jump up onto the top of the shelf unit.  Stay against the back wall and watch for smokers as they will drag you off.  Pistol Hordes, smokers/hunters and boomers. Use shotguns on the tank at point blank range as he climbs up.  Not too difficult to achieve Gold.

The Bridge:
Easiest place is in the room with the ammo and health kits. All 4 players take auto shotguns. Two players stand on top of the boxes, another in the corner by the windows and one in the corner with the television. Use shotguns the entire time as ammo is close. Be careful of cross fire and hitting each other). Not too difficult to achieve Gold.
Our Best Time to Date: 13m 30s

The Farm House:
All 4 players stay in the main room against the wall with the health kits and guns. Its best to use auto shotguns the entire time since it will become hard to start switching guns. The Tank will (sometimes) come through the window but the auto shotgun at close range will generally get good results. Quite difficult to achieve Gold.
Update: Using the large red barn, as described in campaign finale, it is possible to be knocked up on to the top of the roof by a tank. Will take some time and a lot of luck.
Our Best Time to Date: 62m 18s
