Overall good game with a lot of technical issues and a too short story.
Graphics is the best i've seen since bioshock.
The game had a lot of problems with clipping and in the final showdown I keep falling through the floor of the ship - fortunately it was possible to power-jump out through the floor and onto the deck again... this game must not have been tested very well.
I used the lastest Nvidia drivers as well before even beginning the game.
Screen resolution MUST be set to the one used in the game - idiotic programming and the first time i've seen this in a game in the last 5 years.
Sound was often stuttering on a SB Audigy2
Playing the game is great fun however - especially the diversity which is introduced with the many different kinds of vehicles and planes to fly - very nicely implemented.
The suit never really gets too powerfull, but the cloaking feature can be spammed between stealthed attacks too easily to make it much of a challange on hard difficulty.
It's really only with a lot of mobs that it becomes a matter of survival.
E.g. the final showdown in the game can actually be done hit-and-run between stealths
The lack of timers in the game tasks makes it a bit hard to understand the constant reminders of hurrying to this and that - you basically have all the time in the world to complete it, so the stealth method is usually the best.
So the game can be played like the invisible man with a gun and hit and run. Nice feature, but too easy for my taste in the end.
