If you have put the command: !l4d1_survivor all

They are bots ported from The Passing campaign. So they will not be able to follow the player, take damage from the infected and will be ignored. These were programmed to stay in position and defend the Survivors from the vision of the Infected. This is how the final of The Passing works.

If you put this command: !survivor bill

Spawn a l4d1 survivor, but it only works if you are on maps with l4d2 survivors. In l4d1 they will be cloned.

Keep in mind that they will be erased when you switch to another map and there may be a few crash games.

Alright thanks I had problems with the passing and for some reason anything so i reinstalled it and it works thanks mate
