A early homebrew game has been released by thatotherdev.  The objective of the game is to shot the cube workers. This updated version has many changes like split two player mode (Split-screen) and the option to take screenshots now. While its a basic game, you need to remember that this is just the beginning of the PS3 homebrew scene.

• Take screenshots (saved to USB storage devices)
• Bug fixes
