Overview:

Insurgency is the follow-up to the original Insurgency mod--a class-based tactical shooter, built as a Half Life mod, that emphasized realistic-feeling weapons, sound effects, and damage models. Insurgency marks the game becoming a standalone product, built on Valve's Source engine, and includes changes such as the "Light, Medium, and Heavy" body loadouts.
