THE GOOD:Graphics [Water effects most especially]
Co-op is decent. It provides a good bit of fun provided you have a competent team-mate.
Weapon customization is cool. This is perhaps the best point in the game. With a bevy of options for almost all the guns, you can really make a gun yours.
THE BAD:
Gameplay: It is slow and very linear. often being funneled into a single path gets annoying.
Short, linear, slow, scripted campaign.
Sound
Voice acting
Replay-ability
AI: The AI in this game, though decent, lacks and true ability and will fall before you like leaves in a strong wind.
SUMMARY:
This game has a cool idea. An elite unit of two buddies, handing the world its ass on a silver platter.
It has a mediocre execution, however. The gameplay is decent the first time you play through it. Cool ideas like totally customizable guns, and masks give the impression of a deep game. In reality, it is pretty shallow.
The story is disjointed in the telling, with the time line spanning years ...
