Fantastic game that got buried by reviews, obviously because it didn't have a big publisher.
The graphics are top-notch (gears/uncharted quality and yes i am dead serious). Amazing lighting, fantastic textures with great use of normal mapping, very good environmental effects (like dust) and great atmosphere. The black and white first level is genious. The frame rate is rock solid.
The gameplay is also great and expands on the gears formula much more than gears2 actually did. The boomerang adds a new element of depth and the game has more gameplay variety than either gears or uncharted with heavy shooting elements and GREAT close combat dynamics. The "flow" of the gameplay is just right.
The game trounces crap like "Army of two". I urge anyone that likes action shooters to try this game (it must quite cheap now). They might discover true gem.
