Left 4 Dead 2

Left 4 Dead 2 Achievements


As a Special Infected, incap someone who is trying to sacrifice themselves.  

This achievement can be done with 5 people if done right. Have one person be a survivor, while the other 4 (including you) are the Infected. Make sure the Infected team do not spawn until the bridge is raised. When the generator is turned off, have the one player leave the bridge to turn it back on. This is when you and the other Infected team spawn. Have the other 3 Special Infected keep the AI survivors distracted as you attempt to incap the human controlled survivor. It is recommended to be a Hunter, Charger, or Tank to incap the Survivor. Once the human survivor is incapped, you will earn the achievement.

NOTE: The player does not have to be turning on the generator, they only need to be off the bridge.

you can do this with all special infected except boomer and spiiter the best to do this is hiding close generator and remember to be quickly because start the generator take less time

i was able to get this achievement easy on left 4 dead 1, but can't seem to get it for left 4 dead 2. i have tried it many times, but i always spawn a spitter or boomer, whilst on left 4 dead 1 i was nearly always the tank. some help with this achievement would be nice as i dont think i will be able to get it alone. my gamertag is ''Barker Guru'' if you want to add me and i will help you get it aswell. i also have 2 controllers.

I did this one first time. Before you start the generators, make sure you have a boomer bile. Once at the gun on the bridge wait for the four tanks to start climbing up the bridge and throw the bile bomb away up the street. Once all this is done, make sure your friend (who is a special infected is near the generator, A smoker or hunter are the best bets. Attack them when they go to the generator. The tanks shouldnt get you as they are concentrating on the other survivors and the infected will be to preoccupied with the bile bomb. Once this is done, do the same for ur friend.

I forgot to mention that you jump down the girder at the mounted gun so you will completely avoid the tanks.

Easy, 2 controllers. set up for the finale (Since its impossible to become a tank on the finale anymore) There is a room under the stars when you start the middle generator, have a grappling zombie like hunter or charger. And make sure the door is still intact then whomever needs the achievement attack them in the room and it's unlocked.
