Could this be Blackroom? Romero cancelled the original Kickstarted campaign and the game went silent for a couple of years.
John Romero and fellow id Software co-founder Adrian Carmack proudly announce BLACKROOM™, a visceral, varied and violent shooter that harkens back to classic FPS play with a mixture of exploration, speed, and intense, weaponized combat. Use fast, skillful movement to dodge enemy attacks, circle-strafe your foes, and rule the air as you rocket jump in the single- and multiplayer modes. BLACKROOM launches with unique multiplayer maps and robust modding support for the community to make diabolical creations of their own design.
