I am actually surprised that nobody talked about it yet - the small Warsaw (Poland) studio MadMind is creating very (un)realistic survival horror game placed in Hell. From playing the demo I can honestly say that I have never seen game as detailed as this one. It’s great showcase for Unreal Engine’s capabilities.
