Thursday 24-Dec-2009 10:51 AM Build and play custom campaigns from today Valve's released the Left 4 Dead 2 Authoring Tools and Add-on Support, just in time for some Christmas map-making.
Those looking to design their own Left 4 Dead 2 campaigns should download both files via the Steam tools tab, says Valve, while those who'd simply like to play others' creations need only click the Add-on Support package.
The Authoring Tools include applications, utilities, and example files that are useful for building L4D2 game add-ons, the developer adds. Among the many updates and new features are (in Valve's words):
"Gamemode Logic: Designers can now make a single map that can behave differently depending on the gamemode in which it is being played. This can dramatically reduce the file size of Campaign add-ons, as the same map can be used for Co-op, Versus, Scavenge, and Survival.
"Director Logic: Maps can now alter their layout and behavior depending on how "angry" the A.I. director is. The better the Survivors are doing, the angrier the AI Director seems to get. This allows you to base variable paths and other events on the player's skill and current conditions.
"Scavenge Mode Support! All the elements map authors need to support Scavenge in their maps. This includes game props as well as a full example in the form of Deadline 2, an updated tutorial campaign."
