A downloadable game for Windows and Linux

4x0ng is a game where you control a little robot trying to sweep up particles in an overheating nuclear reactor. Here's a video:

See title screen for more info.

This is a playable demo, not quite beta. Feedback and ideas are appreciated. This game is inspired by several Atari 2600 titles, including "Reactor" and "China Syndrome."

UPDATED December 2, 2015 to version 0.92!

Install instructions


Unzip the ZIP file and open the resulting folder. Double-click 4x0ng.exe to begin the game. Xbox 360 game controllers should work if connected via USB.

COMPATIBILITY NOTICE: This game is not compatible with DEP (Data Execution Prevention) on Windows, and will crash unless DEP is disabled for 4X0NG.EXE. It is not necessary to disable it system-wide; you can turn it off per-application. You may wish to consult Microsoft's DEP help page:



You will need to have installed the SDL, SDL-TTF, SDL-IMAGE, SDL-MIXER, and SDL-GFX libraries. Extract the files from the archive; the binary is called 4x0ng.bin.

Known issues on Linux

  • The current directory must be the same as the executable's.
  • Some Linux users may get an error message about not being able to load SDL-GFX. If this happens, try choosing the CONTINUE option. I am working on a fix.
