It's too easy, even on the hardest difficulty... I like the mechanics and the predator bow, but you can cheese the whole game with armor and stealth. Even the predator bow is absurdly powerful because it doesn't alert enemies. The Ai is also atrociously bad. This is just a generic shooter, with a generic protagonist and characters. It feels good to play, but everything else is not exciting.

Only get on a deep sale, if you like the sandbox element and are willing to nerf yourself to have fun.
