In short do not buy this game, there is only a hand full of levels and the entire game will take only and hour and a half to complete, the real challenge in this game is to find any substance.
I enjoyed greatly previous versions of this game and was pleased to see improvements in this, the latest version, but that happiness was short lived, about an hour and a half to be exact. Ding Charvez, the charter you play, could not have foreseen the abrupt credits and game ending going off like a hidden land mine mid way through the..er...well start. And as for the week attempt at a laser puzzle, I would have great reservations that the worlds best anti-terrorist, covert operatives, would have any bother with a 'duck under' the stationary laser beam, duh.
On the plus side the boys at Red storm/Ubi soft have done a good job at trimming down the irrelevant stuff i.e. the weapons stock pile, of guns with little or no difference, the lock pick/electronics kit, and the pointless talkie bit at the start of every mission, we can read!
They have also produced absolutely stunning graphics and realistic game play, if only they done it in a more sufficient amount.
