I finished the game recently and I totally suggest you to look it up, since it's story changes your mind on killing other people ingame. It's metaphorical and subtle events makes it's story so great in the first place. It costs about 20€ on Steam, so if you are sure you wanna spend that much on 6 hours be sure that it takes some time until the story gets really into it's core.
Therefore you will look at this game like it is a meaningless CoD shooter in third person perspective with dull gameplay. I can only recommend it and I assure you, this is no game.
