Alien Swarm Deferred

Alien Swarm Deferred was released in 2012. It's a third-party mod created by Kristjan Skutta a.k.a. Biohazard90. This fork of Alien Swarm has support for deferred lighting and shadows (Similar to Black Mesa). It's among very few Source games that have dynamic shadows not based on projected textures, while still having its source code available to the public. Performance-wise, it is extremely impressive as the mod can support hundreds of dynamic shadows with very little performance impact.
