Valve has announced that Steam Workshop support is coming to Left 4 Dead 2. The developer said the suite of mod and community tools will be compatible with Mac, PC and Linux, starting from “the middle of next month”, which suggests Steam’s Linux beta isn’t too far away.
Intriguingly, Valve said the Left 4 Dead 2 version of Steam Workshop will include an experimental feature designed to “allow content to appear in the L4D2 world even more seamlessly based on the community’s response”. Valve is also working on a new scripting tool to allow modders to really get their hands dirty building all new experiences. These scripted creations will be applicable to current and new maps just as Mutations are.
