The Quake series is a line of first-person shooter video game produced by id Software.
The Quake series is somewhat unusual in that its focus changes frequently; the story of Quake II has nothing to do with Quake, and Quake III Arena has little to do with either of its predecessors. This is mostly because Quake II was originally intended to be a separate franchise ("Quake II" was a tentative title), a plan that was thwarted when most of the other names id Software had tried to use were already taken.
Quake involves a marine traveling through alternate dimensions to prevent an invasion of inter-dimensional monsters, a storyline somewhat similar to that of id's previous game Doom.
Quake II involves an assault on an alien planet, Stroggos, in retaliation for Strogg attacks on Earth. Most of the subsequent entries in the Quake franchise follow this storyline.
