Umbral Anomaly (Spacewar Build)
A downloadable game for Windows and Linux
Requires Steam to play with other players: https://store.steampowered.com/
Note that the game requires two or more players to launch the game, with lobbies of four or more players working during testing.
This was the last worked on build for Umbral Anomaly as of January 15th, 2026. While the game is functional, it is still relatively buggy
While I might revisit this concept, this is where the current build of Umbral Anomaly ends. I hope you enjoy what has been built at this time!
Download
Install instructions
If you are downloading a build to play the game with, select Umbral Anomaly Windows or Umbral Anomaly Linux.
Download your selected version, extract ALL of the files into one folder, and double click the executable contained in the folder. If you are on windows you might get a warning, ignore it and continue.
Note that the game might crash on launch, this is due to a loading bug. Keep trying and it'll eventually load
