Crysis II.
Only a couple hours in.
This is NOT the best looking shooter on consoles. You can tell it would look incredible on a great PC, but since this hardware is over half a decade old, its limitations are notable. It looks very good, but I'd argue the MoH, CoD & BF series looks better, particularly the player models. The Crysis 2 models are pretty good but feel like the graphical settings are turned all the way down.
Gameplay is interesting. The AI is a lot smarter than most games, working together, flanking you, using cover, flushing you out, etc. The only downside is it seems like they hit glitches a bit too often, which is a more noticeable departure than games where they are always doing stupid things.
I'm only playing on the 2nd difficulty setting, which has been far too easy thus far. I really like the use of camo, armor, HUD, nanovision and other items, though it feels like the power-ups recharge way too fast. Perhaps that is due to the difficulty setting. It also gets a bit annoying to hear him announce "______ on" every 15-60 seconds when you toggle one of your power-ups.
Pretty fun game rental. I can't see myself playing it long term, but definitely worth trying out for a weekend or two.
