Left 4 Dead SDK (Authoring Tools)
Yesterday, the Left 4 Dead team released a beta version of the long-awaited SDK!
Today we are opening the beta of the Left 4 Dead Authoring Tools to the public. It is available as a free download for all owners of the PC version of Left 4 Dead, and can be found under the “Tools” tab in Steam.
The L4D Authoring Tools include modified versions of the same tools we used to produce Left 4 Dead.
Using the L4D Authoring Tools, you may create your own campaign maps, character skins, 3D models, sound effects, and music and load them into the game.
Here’s what’s included:
- Updated version of Hammer, the source level editor
- Updated suite of command line compiling utilities
- Updated Particle editor
- Updated Faceposer
- Example maps, common infected, props, and explosives
This release also introduces a pair of plug-ins for SketchUp, a 3D modeling program you may download for free. You may use these plug-ins to create building blocks and props that can be imported into Hammer for use in game levels.
This should greatly increase the number of custom skins, maps, and mods in the coming months. Get yours here: http://l4d.com/blog/post.php?id=2510


Do you make maps? I must see some map making action!
