The Mutation mode, which is a weekly changing DLC game mode, is currently playing the Realism Versus game type and is set to feature the already confirmed Chainsaw Massacre in the coming weeks, but a Steam forum goer by the name of Thegreenthing16 has uncovered a load more of names and details of possible upcoming Mutation game types.



The Mutation mode is easily one of The Passing's selling points and we hope that these turn out to be legitimate variations that Valve puts into practice in the coming months. This is a great way for Valve to keep users buyers active and satisfied

The Mutation games modes are needed for the achievement: You need to play 6 different variations. So this means, 6 weeks of fun

Who else will be following valve's challenge in order to complete L4D2?
