An ansolute surprise of a game, I bagged this recently first hand for £9.99 and it was simply a steal at this price, it would be a crime to have bought it.
To say this game is an unsung hero of gaming is a huge understatement, its an absolute masterpiece of a game, the way the shoot-em-up, stealth-em-up and beat-em-up elements are blended together is simply genius.
Gorgeous graphics, well paced set pieces excellent CGI, great story that sheds light on the mysterious Riddick character, like how he got his "eyeshine" vision....
This is THE best game I've played since HL2 (which i purchased on launch day), its perhaps miles better than hl2 in areas, hl2 is only a shoot-em-up, riddick is effectively three games combined into one brutally fanstastic game...
This is the best example of "co-developement", yeah its on the XBOX but the PC version hardly suffered at all...
Don't waste any time, get it now if you haven't already...it would be a crime not to...
