Those of you amongst us who enjoy slaughtering wave upon wave of the living dead – and who in their right mind doesn’t? – will probably be aware that the latest DLC offering for Left 4 Dead 2 became available for download a few days ago. Entitled, The Passing, the content pack introduced a brand new campaign to the co-operative zombie shooter but also added a new component called Mutations.

Mutations are essentially new game types that will delivered to the game’s servers on a weekly basis, each one offering players a variation on the standard modes – the idea of which is to keep the game fresh and fun for players – after all, variety is indeed the spice of life.

Valve planned to unveil new mutations on a weekly basis via it in-game message system – but of course the internet has other ideas – A user on the Steam message boards, Thegreenthing16, has been busy poking around in the system files of the PC version and has uncovered a list that seemingly reveals a good number of the Mutations.

The full list of Mutations is as follows:

  • Chainsaws
  • First Man Out
  • Four Swords Men
  • Hardcore
  • Head Shots Only
  • Last Man on Earth
  • Linear Scavenge
  • M60s
  • Max Specials
  • No Health Versus
  • Realism Versus
  • Temporary Health
  • Ultra Realism
  • Versus Survival
  • Vip Target

He also went on to detail three of the Mutations:

  • Guard the Gnome: A co-operative mode in which a Gnome spawns at the beginning, you need it to to make it   through the levels. Zombies will go after the person carrying the gnome.
  • Bleeding Out: Another co-op mode, all players start will temporary health that drains fast. There are no Medkits, only pills – lot’s of pills. The mode includes lots of random panic events.
  • Realism Versus: Self-explanatory, this is Versus mode implemented with the realism parameters.

While this list has yet to be confirmed by Valve, we already know that Chainsaw Massacre & Realism Versus are legitimate Mutations, which adds a level of authenticity to the list. At the time of writing, there are still 7 mutations listed that have yet to be named, but we’ll be sure to update the list once the information becomes available.
