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 Alien Swarm has support for deferred lighting and shadows (similar to Xengine Xengine). It's among very few Source 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.

Icon-Important.pngImportant:Alien Swarm Deferred's lighting implementation and Black Mesa's are completely different, for example MSAA is not supported in Black Mesa while in Alien Swarm Deferred it is!, however it is highly recommended that user uses post-processing alternatives such as FXAA instead as deferred lighting/shading in general works better with post-processing anti-aliasing methods.
Warning.pngWarning:Alien swarm deferred's lighting implementation nukes lightmaps, aka it will disable all baked lighting and the world will only receive realtime lighting and shadows!
Note.pngNote:In Lambda Wars Lambda Wars it was changed so that deferred lighting blends with lightmaps instead of disabling them.
