Rock Solid Brown Colored Quake-like Boomer Shooter. Lots of Brown Sewers, Brown Castles, Brown Caves, and Brown Corridors. Some Shake ups aesthetically might've been nice. This is the kinda game where all the little details add up to something special.

Like how every level takes direct inspiration from a real life place in Russia. When Duke Nukem 3D came out, gamers back then loved how levels felt like real places rather than abtract mazes. This is the natural evolution of that.
