Microsoft have released the third developers diary for Gears of War 2, the upcoming sequel set to be released in November for the Xbox 360.

In Gears of War 2, players continue as Marcus Fenix, a reluctant war hero and leader of Delta Squad, six months after the events of Gears of War. The last cities on Sera are sinking, swallowed by a new Locust threat from below. A massive counterattack is humanity’s last hope for survival.
