Important:Alien Swarm Deferred's lighting implementation and Xengine'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:Alien swarm deferred's lighting implementation will disable all baked lighting and the world will only receive realtime lighting and shadows! 
Note:In 
Lambda Wars it was changed so that deferred lighting blends with lightmaps instead of disabling them.

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 
Xengine). 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.
Important:Alien Swarm Deferred's lighting implementation and Xengine'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:Alien swarm deferred's lighting implementation will disable all baked lighting and the world will only receive realtime lighting and shadows! Note:In Lambda Wars it was changed so that deferred lighting blends with lightmaps instead of disabling them.Features
New since Alien Swarm:
- CSM
- Real time deferred shadows and lighting from light_deferred and light_deferred_global entities.
- Light cookies
- Now light_deferred is capable of projecting textures with cookies.
Blinn–Phong reflection model- New reflections on Phong materials, somewhat similar to specular from Xengine.
- Volumetric lighting
- Light_deferred is capable of enabling volumetrics that react to the environment in real time.
- Source shader editor
- Make and edit shader graphs in real-time, in-engine.
- Light editor
- Edit your map's light entities dynamically.
