Beast mode in Gears of War 3 is best described as "inverse Horde." It has you playing as the Locust while you go after waves of CPU-controlled human enemies, who pack Lancers, auto-turrets and even the Hammer of Dawn. As you progress through each wave, the humans become tougher -- both through their tactics and arsenal of weaponry at their disposal, not to mention the ticking of the clock menacingly counting down to zero in the background throughout each wave. And after my time playing this new mode, it's a brilliant fit for Gears of War.
