Valve’s latest mutation for Left 4 Dead 2 is one called Bleed Out Versus. It is a mutation that gives the Survivors non permanent health, meaning that your health is constantly dropping! You’re best served just rushing through the maps with this mutation on. It looks like a really hard one. Give it a try!

Next week’s mutation is Healing Gnome. This sounds like an interesting mutation. I expect it to mean that holding a gnome heals you, but I could be wrong. What do you think? Leave your thoughts in the Comments!
