Strong story, fast paced shooting action. And if you cannot shoot, then there is your RECON, hacking device enabling you to remotely control various devices you meet on your way through the dark halls and corridors of Alpha Prime. If that's not enough, you can drug your mind and sharpen your senses by injecting small dose of hubbardium. And all the time you will be surrounded by physical world in a very literal sense, because almost everything that moves, moves thanks to advanced realtime physics algorithms.
