This game absolutely rocks. Other than a kind of slow and boring turret escort mission and an abrupt ending, the game moves so quickly, helped by its 5-6 hour campaign. The story is serviceable.

Gun selection is small, but there's some really cool ones, especially the designs of them. I especially like how some of them seem to alter their appearance with upgrades. The cover based gameplay is given a little shakeup too compared to normal Gears of War type combat with hiding vertically on ledges and shooting up or downward. The small shift in gravity and perspective leads to some creative enemy disposal methods like tossing a grenade up, or just climbing over the ledge and punching the guys in the face.

The star of the show though is the jetpack which is so cool. After being given the ability to fly, levels open up and let you boost around freely in the skies and land on the ground to just take in the landscapes. While I wish more levels took advantage of this, I think the novelty of some large scale base siege set pieces is neat. Taking out turrets around and then flying into the base to wreck it and its forces from the inside is such a huge power fantasy. I like this one a lot, might not go back to it anytime soon, but I'll definitely be thinking about it for a while.
