Aliens: Colonial Marines is a squad-based first-person shooter in which the player controls four Colonial Marines, each with a different personality and primary weapon. Each player character can carry additional weapons including a flamethrower, pulse rifle, smartgun, pistol, RPG, and many types of grenades. The player controls one marine at a time, issues orders to the others using context-sensitive commands, and may switch between characters at any time.
Replaces Mk2 Pulse Rifle model with Mk1. It's only visual change. Made it by replacing Mk2 mesh with mesh from Hudson's PR and removing Hudcon's decals.
