The gaming industry is a volatile place, and a lot of games that seem like a lock for getting released often end up in the waste bin. Some become famous – like Black Isle’s Torn or Paradox’s Thrill Kill – but there’s plenty of lesser known titles that fall even deeper into the hobby’s cracks. Such was apparently the case with Grin’s planned Xbox shooter, The Unknown.

Grin, a game developer based out of Stockholm Sweden, attempted to get this published in 2004 and used the above linked footage as their pitch. Focusing on “arcade style” FPS gameplay by keeping track of kill streaks and adding them to your score, it certainly could have found an audience among old school shooter fans that craved something less cinematic and more DOOM. It could have also piggybacked off of the success of 2004’s Painkiller, which was another score-based shooter.

The demo, played by the youtube channel PtoP – which makes it its mission to preserve gaming history – seems to take place entirely within a submarine and has the player fending off aliens with a gun that (at least to me) looks and sounds a lot like the assault rifle from Unreal 2. A boss fight against a spider/mushroom hybrid monster takes place within the final level.

Grin’s last game was the 2009 Bionic Commando reboot that came out in May of that year.
