Fun, fast-paced game. It's a bit unpolished, and it's very short (can be beaten in under 2 hours, and doesn't take much longer to get 100% achievements), but considering how much action it condenses into such a short experience, I think it's fine. It doesn't overstay its welcome. If you like the sound of million-mile-an-hour first-person shooting and platforming, with a grappling hook, while metal and electronic music is blasting, then give it a try!
