Forget the old Splinter cell where you hid bodies around and if you triggered an alarm you had to start all over again. Sam Fisher's gone Rambo on this one and goes around killing foes without hiding them. The 5th installment really takes the game to unprecedented levels of game play variation that might not be every one's cup of tea.
Here on, Sam takes the battle personally into his hands and goes around killing and the bodies really pile up in this one. The cover system makes a start in this one. About time... Your foes are as dumb as you are powerful and tactical. The AI is stupid in the sense that seeing a dead body they will gather for a minute and continue their patrols the predetermined way. There is no change of approach which makes it kind of dull.
The AI however shoots very well once they spot you. So gun fights can be pretty rough. once again the missions vary as you globe trot around this time. the weapons package is up-gradable and the enemies this time really flinch once you shoot a light and plunge the area into darkness.
This one is 70% action and 30% stealth. But that fortunately doesn't change much, as this game everything apart, is still Stellar.
