Valve updated Left 4 Dead 2 to support Steam Workshop today, making it easier to find and install community-created content for the co-op zombie apocalypse shooter from within Steam.
Left 4 Dead 2's Steam Workshop is already filling out with community-created campaigns, weapons and Mutations. While current Workshop submissions consist of relatively minor mods like a quieter chainsaw and custom icons for each survivor, Valve expects "thousands more items and skins already created for the game" to round out the community-made offerings.
The Steam Workshop update coincides with a batch of new Left 4 Dead 2 fixes, which are detailed on Steam.
More information about creating and uploading custom content for the Left 4 Dead 2 Workshop are available at the game's official blog.
