 Mankind discovers the secret of  slipgates  called teleporters. However, they re misused by some strange force code-named  Quake , which uses the slipgates to send hordes of warriors to earth to take over the whole world. A marine special unit, to which you belong, is instructed to seek and kill  Quake  and his minions - somehow  Quake  knew about the plan and erased the whole unit - except for - surprise! - you. You throw a round of shells into the shotgun, sharpen your axe and engage to the strange and ancient worlds of  Quake s realm. You learn that  Quake  is actually Shub-Niggurath, a hideous demon and witch-goddess, and that the monsters are her breed! You decide to collect the four runes of magic to find Shub and kick his god-forsaken ass!
