New and improved Mutation System
Valve has released an Expanded Mutation System forLeft 4 Dead 2, which will first be available with a beta release before wider distribution. Essentially,this is an improved scripting systemthat will allow modders “to go past modifying existing scripts and write custom script logic, spawn and control entities, and much much more.” I’m no expert, but that sounds like a potentially big deal knowing how creative the community is.
The company says that with the featured Squirrel scripting language, new Mutations forLeft 4 Dead 2can “rival all-new game modes in complexity.” There’s a Valve-made example, a survival mode called Holdout,and a wikito get modders up to speed.

Once this is out of beta and in the Steam Workshop,the already great libraryof mods is only going to get that much better.
