An enemy with the codename ''Quake'', which is believed to come from another dimension, is using teleporter gates to invade Earth. The player takes the role of a nameless soldier who arrives at his base only to find out Quake has overrun it and killed everyone. Somewhere in the base there must be a teleporter to Quake's realm. The mission is clear: take the fight to the enemy, overcoming countless hordes of monsters, and exact revenge.
