Played a couple of matches last nite after work. Here are some brief observations:
-Picking up and using turrets (switching into a Gears over-the-shoulder mode) is pretty cool
-Graphics get the job done, ground textures look pretty nice but it's the Gears syndrome again: Gears has spoiled me for good graphics, so I'll compare everything to that
-The maps seemed to be pretty small, and all the action was very up-close
-Saw some framerate drops in the beta
-Not a fan of the ATV... doesn't seem to have the speed/maneuverability I expected/wanted
-Proximity mine: AWESOME
