Valve has revealed the Mutation Mode in Left 4 Dead 2 this week, and it's called Bleed Out.
Sounds ominous, huh?
According to Valve, in Campaign mode, your character will have "no permanent health, only temporary health" and it is "continuously ticking away".
There will be no health packs for the getting, only pills and adrenaline.
Who knows what the sick, twisted minds at Valve have in store for us next week. Gabe only knows.
Last week it was Realism. Hopefully, you enjoyed it.
