I pre-ordered this for the full price a few months before its release as I had played through a bit of Crysis on PC and Crysis 2 on Xbox 360 and really enjoyed both games. After loading the game up for the first time I must say that although the graphics are quite stunning, the game did feel a bit too much like the second one (Which I guess, if you enjoyed it may be a good thing) but was it worth the Â£45 price tag I paid back then? possibly not. Having now played through the entire game I'm pleased to say that it did get better, you are given many different tactical decisions on how to approach combat (Stealth, All guns blazing etc) and this was both enjoyable and also added a real re play value to the game.
The series takes a lot of ideas from the original predator films and you literally do feel like you are hunting down your enemies, It's both visceral and extremely stylish and a hell of a lot of fun. Weapons are upgradable as are your stats so there is a lot of versatility to suit most play styles.
For the amount of game you get It's not the longest at around 10 hours or so play through but re play-ability wise it ranks quite highly I would say that this is worthy of your game collection and at Â£15 on here I would say that it is a bit of a bargain.
