Just discovered this game from DasTactic's video, picked it up and it's a lot of fun. Gameplay is like Hotline Miami but with more stealth mechanics like darkness/turning off lights, moving bodies, and nonlethal alternatives. Also you can pick a loadout complete with a sidearm and some nifty gadgets like claymores and throwing knives. The enemy AI is actually fairly good, I've been impressed with how enemies fan out, cover each other, and don't just blindly run around a corner where their buddy just died (like in Hotline Miami).
Oh, one more thing to mention for the Groggies: One big advantage this game has over Hotline Miami is a quicksave system. Really helpful so you don't have to play the same part over and over ad infinitum. It's also quite a bit more mid-paced in comparison and more reliant on good tactics than twitch reactions, though twitch reactions help out in a pinch.
Well worth the asking price so far.
