I downloaded the demo for the PC. The graphics are amazing, the control system is fairly intuitive, and the way you can interact with your environment is a step up from most FPS games I've run across.

They've managed to set it up so you can utilize your environment for a greater kill ratio, often using the powers your character can accumulate during gameplay. Got three enemies standing in a partially flooded room? Zap a bolt of electricity into the water and you'll frag all three at once. Got a really tough opponent? Set him on fire; he may run for water if there's any around and jump in to extinguish himself (great AI). Then you can switch to electricity and finish him off once he's there.

Plus, the storyline is pretty unique. You survive a plane crash in the Atlantic and swim to a nearby lighthouse. There, you find a bathosphere that lowers you down into an underwater city founded by a guy who's scarily like Ayn Rand. His utopia has gone completely haywire, of course, and you'll have to jack up on genetic modifications and weapons in order to survive and get the hell out of there.

So all in all, solo play should be fun, with a strong storyline, lots of action, and a great environment to explore. Plus, multi-player PvP should be a kick in the ass.
