From the makers of Hitman; inspired by some of the greatest crime movies around - think Michael Mann / Tarantino / Scorsese; great trailers and very favourable previews in gaming press...
All of these aspects add to the utter disappointment experienced when the disc slots into the console. The opening levels are dull - unimaginative settings, poor graphics, rubbish artificial intelligence (read: no intelligence) and no emotions at all evoked from the awful scripting and voice-acting of the two lead characters. I've never felt so hemmed in by invisible walls, with the only distraction from the onset of claustrophobia being the constant bugs that plague the game. The cover system is similar to that used in many other games - Rainbow Six Vegas, Splinter Cell etc - but despite having these excellent examples to work from the developers have still managed to implement it with the kind of incompetence that would usually be reserved for "junior officials" at Her Majesty's Revenue And Customs.
The only film that the game does manage to do justice to is in fact, Die Hard II. Specifically the scene where Bruce Willis' wrong-place/wrong-time LA cop is chasing down William Sadler's gang of snowmobile-riding terrorists. Brucey bags one of their weapons and trains the sight on his target, only to hit nothing but air. They're firing blanks! Which is exactly what happens regularly in Kane & Lynch.
Admittedly I haven't attempted the game in co-op mode or multiplayer, so you'll have to rely on the wise words of another reviewer for those aspects... but unless the developers treated the single player mode like a mock-GCSE exam - starting and finishing it overnight before the big (I almost typed "bug" there... would that really have been classified as a typo?) day - then I would be nothing short of astounded.
One last thing to mention is that the squad command system is lifted almost exactly from IO's ace and highly underrated Freedom Fighters... but alas the implementation is on a par with the other faults of the game.
Do yourself a favour and pick up Hitman: Blood Money, Freedom Fighters, Michael Mann's 'Heat' on DVD, and for a truly magnificent next-gen shooter experience - Call Of Duty 4.
