Freeman observing Alien

The Alien Grunt is the main protagonist of Half-Life Xen Warrior. He is one of the many Alien Grunts sent to Black Mesa by the Nihilanth.

He is born prematurely when his cocoon breaks on the usine seen in the Interloper chapter. He then goes to Earth via a teleporter.

He has only one weapon, the Hornet Gun. He can gain health by feeding on corpses, and sees enemies in a green halo, while he sees himself and his allies in a red halo. The G-Man is seen in a blue halo.
