Basic info:
Graphics: AMAZING! great animations with amazing backgrounds and a lot of polish to it!
Gameplay: Sharp controls, lost of humor, intense cut scenes, and a lot fighting with a sense of stealth.
Enemies: very good, smart, and aware AI
Online: Very fun with enough game to keep you happy, with a "Mute all" option for the giggling 10 year olds in the background.
Glitches: not many, and non that will affect you except maybe once or twice.
short review, nothing to say except AMAZING!
** IF you like suspenseful action with hints of stealth, loaded with funny humor, and a 10 hour campaign with endless online hours, then you will like this game.
ATTENTION: since this is a sequel many will ask: "standalone?"
well, if you play the first game then you will understand maybe 2 or three more jokes in U2, but if you just want U2 that's OK, you still will have fun with U2.
