Continuing the storyline from Quake II (1997), once again it's up to you to engage the alien race known as the Strogg.
During the bloody war between humans and the nightmarish race of the Strogg, a lone marine infiltrated the planet and assassinated their horrific leader. The humans discover that the Strogg are not so easily defeated, however, and that their only hope may rest on a marine that is no longer entirely human.—Chris
