This is a well made old school linear shooter set in an alien setting. The guns are quite fun as they are all alien weapons. The level design gets rather crazy, with portals, changing gravity and areas you can only reach using your ghost form. Then there are these drone sections, where you touch a button and around you forms a flying vehicle. These sections could have been vastly improved in my opinion, as the enemies you face during those sections are terrible and it is not always clear where to proceed. You can't take much damage either, which gets annoying quickly as the enemy drones fire tiny homing missles and some weird bombs, while moving like they have no weight whatsoever. The canons you can fire in this flying vehicle are inaccurate and deal way too little damage (you have to hit a normal enemy soldier like 5 times or so to kill him). The gameplay while running around on foot is usually better. There are some parts where the game tries to be a horror game, but it did not really work for me and all in all those parts do not make that much sense in the story the game tells. I did not actively dislike the story, it is fine, but I hated the main character tommy and shook my head several times while he was talking some nonsense again. It is worth giving this game a try, you may end up liking it more than I did.
