Gears of War 2 ended with the destruction of Jacinto, the last remaining human city on the earth-like planet on which the series is set, and the remaining survivors now reside on a converted aircraft carrier called Raven's Nest. In the final chapter of this epic third person shooter series, mankind is on the verge of annihilation.
But despite their bleak outlook and small number, the human soldiers of Delta squad continue to wage war against the nightmarish Locust Horde of the first two games. They’re rewarded with fresh hope of salvation when they receive word that Adam Fenix - the father of legendary combatant and series protagonist Marcus – isn’t dead as previously thought and may have found a means to destroy their great enemies.
