I have to add that this title has been in the making for a good 3 years....so it is unfortunate Psi-ops reared its head almost simultaneously.
Controls are very like Timesplitters and it isn't that fiddly once you get into it.....just trying it myself now.
Also noticed Gamespot have a plethora of extra material including a brand new video in this section
