Actually, It's been made to be on a PC.
Maybe we could see it hitting the PC?
Sure, the game itself isn't a Timesplitter, Half-Life, Halo, Killzonw, 'call your Best FPS game'. And is a real downside, but it's not so terrible.
But the story, the characters, graphics and content makes up for it.

And I still don't get how the hell you play shooters with keyboard and mouse.
I just can't...(ok, I just don't want to. Since double analog seems to suit me much better.)
