Left 4 Dead 2 SDK Released Just In Time For Christmas

Left 4 Dead 2 Authoring Tools Released to PC Community Today

December 23, 2009 – Valve released Left 4 Dead 2 Authoring Tools and Add-on Support today. The release, coming just before Christmas, opens up Left 4 Dead 2 to a world of community modding.

Valve has always been highly supportive of the modding community. The original Half-Life came with a Self Development Kit (SDK), allowing gamers to create everything from Counterstrike to Day of Defeat to They Hunger and other classic mods. Since then, Valve has continued to create modding opportunities for PC gamers, incubating an entire culture of self-creation.

Left 4 Dead 2 follows the exploits of 4 survivors of a zombie apocalypse as they try to make their way from Savannah, Georgia to New Orleans, Louisiana. The game’s 5 campaigns take place across a large range of settings, from city environments to swamps and carnivals.

The SDK will allow gamers to design their own Left 4 Dead 2 game maps. The development kit now includes Gamemode Logic, which allows maps that can behave differently across numerous modes. This is a direct result of Left 4 Dead’s development kit, which did not allow multiple game mode’s on the same map. Instead, separate files had to be created for each game mode, wasting space on gamer’s PC’s.

The SDK also includes Scavenger mode support and Director Logic, which allows gamers to base variable paths and other events based upon player’s skills and weather conditions in the game.

Gamers who want to play modded levels but don’t want to create their own can install the add-on support package, which is available in Steam’s “Tools” menu. It looks like many gamers will be very happy this Christmas thanks to Valve.
