Hi! i was thinking that left 4 dead doens't exsactly has a exsactly "not-reward" for leave some one die. thius game it's based on cooperation, but in essence, is "help me" than "help us". one player needs the other three, but the other three really need to rescue everyone on extreme situations? why don't just use the incapped survivor has a pipe bomb or stuff like that.
i am not asking for some "health Punishment" or some unrealistic punishment like "blindness" or "time Bomb". just someting that reminds you "we shouldn't leave him die"
