Alien Swarm appears to use the L4D1 or 2 Source engine based on the DX9 video card minimum requirement. Which to my knowledge don't yet support modding. A big part of AS is the release of game code to help modders creating Source engine mods with Steamworks support, it doesn't seem particularly helpful to release something to help people mod a game engine they can't mod yet. That was rambling, I apologize.
