File:Quake1.gif In Quake, the Grunt is a hostile soldier, rewired with a probe in his brain that gives him pleasure with every kill that he makes, armed with a Shotgun. They are the first Enemies encountered in Quake. They traditionally appear only in the idBase levels, but they also appear in E1M2: Castle of the Damned. Unless gibbed, they drop a Backpack containing 5 Shells upon dying. Grunts seem to have quite an affection for Rottweilers.
