Through the
Left 4 Dead Blog, Valve has announced it will release a new update for its zombie shooter some time next week.
Focusing on custom campaigns, the update will provide mod authors with non-beta mod tools, which will now include source files for all of Valve's campaign maps, along with an example campaign add-on tutorial map.
The update will also allow content creators to use a new framework that will package their campaign content into a single .VPK file. These can then be installed by double clicking on them, or dropping them into Left 4 Dead's new 'addons' folder.
Lastly the update will rework the game's matchmaking system, providing support for these custom campaigns, while also making it easier to create a lobby.
