doesnt live up to hype
the graphics are great but very few people have a good enough cpu to run it good on even medium settings. graphics for me were not that important. shocking i know for some who seem to play games because they look pretty and not because they are fun. luckily this game is very scaleable and i could get a good frame rate on low settings.
physics
the physics in this game are really no differant than half life 2s. you can pick up most things and throw them around, hit people with them, or just trash things for your amusment. nothing new and nothing revolutionary here.
nano suit
your nano suit basically gives you super human powers. ive seen this in the jedi knight games, system shock, deus ex, and about 1000 other games.. only you have less powers than you do in those games and more limited energy. the speed in the game is kind of useless because it drains the energy so fast. but it can come in handy some times. the strength is pretty cool because you can pick guys up and throw them or punch them for 1 hit kills and jump real high. its hard to do this on hard setting(i played the game on hard) because you die so fast without your armour power or cloak on. armor basically allows you take twice the amount of damage and which i think is the best skill in the game. cloak is very good because you will need it to hide or sneak up on enemys. i think they could have done more with the suit and made it better and more useable. but most the time you simple hide behind something with your armour on and shoot people without using your other powers that much other than cloak.
having said all that the game was still very good. the single player has plenty of mission for you to do and the multiplayer also gives you something to mess around with. but this game isnt revolutinary and is nowhere near as good as people are saying it is.
