File:Q4.png In Quake 4, a Machine Gun Guard is a Guard that has a Machine Gun for a right hand. The gun appears to be based off the regular Machine Gun, as a magazine from a regular one can be seen on the right hand. Like all Guards, the Machine Gun Guard defends areas that don't need protection by powerful Strogg. Machine Gun Guards appear in the first level and appear in almost all of the levels in the game.
