“Swarm Dynamics“ Source Engine Test Demo by Gray Horsfield

Veteran Valve developer Gray Horsfield recently left the company. The pioneer of Valve’s Cinematic Physics system and L4D2’s zombie gibbing system, he had done work on HL2:EP2, Portal 1 and 2, and the L4D series. This past January, he posted up this video, showing a test demo for a dynamic swarm system, set inside a strange map bearing eerie similarities and parallels to Valve’s Half-Life series.
