Depth Dwellers is a relatively unknown early 3D shooting game that was probably the victim of bad timing: It was released only a few months after DOOM. The game engine developed by TriSoft is somewhere inbetween Wolfenstein 3D and DOOM in terms of features and abilities. The game itself is fairly generic, with not a lot of unique features, and only passable graphics for a 3D game.
Overall a decent effort from an unknown development team, but really there's not much reason to play this instead of DOOM. It's not quite as "AWSOME" [sic] as the registration screen suggests.
