Gears of War is indeed coming to the PC with new levels and features, including the cool fight with a Brumak (look at pic below). Think of a huge reptile but with rocket launchers on its shoulders. Awesome stuff. Gears of War will be for Windows XP and Vista users. Thank god they didnt make it a Vista only game...

The demo shown at the conference was all about the Brumak battle, which seemed pretty freaking brutal. The Brumak is a huge beast controlled by a grunt sitting on his back using controls assumedly wired into the monster's brain. When Marcus and friend ran into the arena the beast immediately started moving around firing all weapons. Cliffy B, who was driving the game, showed how easy it was to connect to a friend over Windows Live and then proceeded to get shot about a million times. The game basically had to be on God mode so we're pretty curious how difficult this creature really will be. The area where he was hanging out didn't exactly have a lot of cover, especially since the creature towered above the human figures and also all of the concrete pipes scattered sparsely around the area. Hiding behind those things didn't seem to help too much.
