Like the zombies it's filled with, Left 4 Dead 2 just won't stay down. Valve continue to update their co-op FPS with new features - this time shoring up the game's Steam Workshop support with an official release of their Extended Mutations. In effect, they've mutated the mutators to provide advanced scripting tools to the community, allowing them to tweak rules and create new game modes. Like adding tiny, shrunken undead . They'd be cute if not for the biting.
Valve say they'll be highlighting some of the best mutations on the official blog later in the week. For now, they recommend Holdout: "It is a multi-map Mutation that includes the concept of resources and buildable items. It was created to showcase some of the functionality of EMS and as a byproduct, it is pretty damn fun." Valve plan to continue supporting the top community mutations through official servers.
This latest update also marks the full release of other beta features, including Linux support - which has now been rolled out to allow testing on further builds and distros. You can find the full patch notes here .
