Mankind is at war with the Strogg, a hostile alien race planning an invasion of Earth. To prevent the invasion, humanity launched a preemptive strike on the Strogg homeworld...it failed, but you survived. Outnumbered and outgunned, fight your way through fortified military installations and shut down the enemy's war machine. Only then will the fate of humanity be known.

QUAKE II

Developed by id Software in 1997, Quake II is a critically acclaimed first-person shooter and sequel to Quake that deviates from the original by introducing an entirely new science fiction narrative and setting.

*Quake II now includes the main game and both expansion packs: The Reckoning and Ground Zero.

Story

Mission Pack: The Reckoning

In the first official expansion pack for Quake II, you are part of an elite commando force that must infiltrate a Strogg site. Once inside, you must scour industrial landscapes, crawl through waterways and air ducts, navigate treacherous canyons teeming with vicious mutants, stow away on an alien spacecraft, and destroy the enemy's secret moon base.

18 New Single-Player Levels
7 New Deathmatch Levels
3 New Weapons - Ion Ripper, Phalanx Particle Cannon, and Trap
New Enemies and Power-ups

Mission Pack: Ground Zero

Taking out the Big Gun sounded simple enough, but the Strogg were waiting.

In the second official expansion pack for Quake II, you, and a few marines are the lucky ones. You've made it to the surface of Stroggos in one piece and are still able to contact the fleet. The Gravity Well, the Strogg's newest weapon in its arsenal against mankind, is operational. With the fleet trapped around Stroggos, only 5% of ground forces surviving, and that number dwindling by the second, your orders have changed: free your comrades and destroy the Gravity Well.
