great entry, has that "doom 3" gameplay scary feeling of switching between a flashlight and a gun to defend yourself that i like a lot, but with a "metro" vibe. Also the game is really pretty, the low poly models and the general vibe works well.
Some Feedback: i think the UI doesn't match the cool aesthetics of the game, looks a bit bland. Also the menus are broken with my current screen resolution (1366*768), with many buttons and info being off screen. Also i think it needs some visual indicator for the health.
Had a lot of fun with it, the change in scenery at the end was a nice surprise and running around with a knife because all my ammo runned out was an adrenaline inducing moment :P. Also the intro elevates the experience a lot
