It's not really what i expected.
But upon playing it, i realized it was nothing like an FPS. The combat is very dull, most enemies can be killed from a few shots from your shoulder cannon, which just involves holding down the auto aim button and firing away. There's also a lot of walking to do when you have to travel from one place to another. And you will be watching your predator walking around in a rather odd way.
Another thing is, that you can't choose if you want to be a human or alien, you start of as a predator which cool as it may seem, is rather boring.
The environments are huge but rather repetitive. In short, you will get bored of this game really fast.
