I checked this out at work yesterday, and was rather appalled... Many many problems, just from playing it a few minutes.
-Horrible framerate. Seems to drop near or below 10 fps frequently.
-Hard to find where you're going. There's no map, and you start out in this labyrinthine set of rooms and offices that all have multiple exits, and nobody tells you where to go.
-You can't talk to anybody... all these people are wandering around but you can't interact with them for some reason.
-Your character stands like he's been on a horse too long... his feet are about 3 feet apart hehe.
-Targetting is really strange.. you have to "flick" the right thumbstick in the direction of whatever you want to target, but that flick is really innacurate.
-While flying around in my little shuttle pod at the very start of the game, I was told specifically not to run into the giant alien spaceship, so of course I did. I "collided" supposedly, which brought me to a complete stop. No other visual or audio clue at all. And then about 5 seconds later I exploded. 'Twas strange.
The writing is all right, and the voice acting was pretty good. Some humor to it, but the gameplay just seems horrible, heh.
