Quake II

Quake II is a computer game created by Id Software and published in 1997. It takes place in the science fiction universe introduced by Quake and, although it is not a direct sequel to that game, the events in Quake II can reasonably be assumed to take place after the events in Quake. A counterattack has been launched against the home planet of the hostile Strogg civilization in order to forestall an invasion of Earth. The landing does not go well (to say the least), and you are left to achieve the mission objectives alone.
