An excellent stealth game hidden under a shitty action game. To access the stealth part of the game properly you have to actively constantly play in a slower, more difficult way. You are not really punished for being caught or even just running and gunning, the combat is bad but your character is just such a powerhouse that you can fight off hordes of enemies.
If you have the self control to take the tough road and not use your overwhelming combat abilities and engage fully with the stealth there is a gem waiting for you.
