[BreakABone]

Well as some of you know The Passing DLC released a few weeks back, and as part of the package came mutations which are like modified game modes. So far we've seen Realism Versus and this one is a survival mode of sorts where your health is always going down, and no way to refill it out than pills/adrenaline.

Someone found a leak of all the mutations, and some of them sound really boss

Chainsaws (coop) - Everyone starts with a Chainsaw (unlimited fuel) and a pistol (unlimited ammo), there aren't any other kinds of weapons spawning, so it's just what you have at the beginning.
Four Swordsmen (coop) - Kinda like Chainsaws, except you start with katanas and no pistols, and there are only S.I., no Commons.
Hardcore (coop) -If everyone dies, you have to restart the campaign, so no restarting maps, you have to restart the whole thing!
Headshot Only (coop) - Self descriptive, commons only die with headshots.
Last Man On Earth (singleplayer) - It's you... against the S.I. (extremely scary)
M60s (coop) - Survivors start with only M60s (limited ammo) and a Desert Eagle, once you run out of ammo, you're screwed.
Max Specials (survival) - It's survival, with 8 S.I. at any given time!
Bleed Out/Temp Health (coop) - Everyone starts with 100 decaying health (pills-like), there are no medkits, only pills and adrenaline.
Protect the VIP aka Gnome (coop, versus) -There is a gnome next to you at the beginning, carry it through the campaign, person carrying the gnome can't use weapons and the gnome attracts infected!
Realism Versus (versus) - You already know what this is, versus with realism modifications.
Linear Scavenge (scavenge) - 2 Cans spawn, get those 2 in and 2 more spawn, proceed...
No Health Versus (versus) - No medkits, no pills, no adrenaline.
Versus Survival (survival) - Self Descriptive, it's a lot of fun.
Madness (coop) - There are TONS of common infected, they are VERY angry and there are no S.I., you have enough trouble as it is.
Versus Coop (versus) - It's coop, with a twist, you play as the infected as the bots try to make it through the campaign alive.
Realism Scavenge (scavenge) - Self descriptive, scavenge with all the realism twists.
