As we had anticipated last week, has been active since yesterday the new Left 4 Dead 2 mutation called "Versus Bleed Out," available only to owners of the DLC "The Passing". This new mode will force the opponent weekly Survivor have to survive without medicine or medical kit and the red energy bar already has come increasingly with the passage of time, while the Infected will always delete them as soon as possible. The mutation of next Friday will be "Healing Gnome."
