Putting the Science back into First Person fiction

Put your hand up if you played a first person shooter recently. Keep it up if it wasn't either of Halo or Call of Duty, or even Battlefield Bad Company. See I have a confession to make: I have played all the Halo but I have not played a single Call of Duty Game ever (except for the odd Call of Duty 4 match at the local LAN). Now before you start calling foul that FPS don't 'work' on consoles, I'm going to ignore you and say that 2011 is going to change all that.
