You are a resistant of the resistance group M.A.R.S. [Mars Active Resistance Squad], you must steal the plans of the Olympus mount base to prevent a war against the Earth. You and your antigrav bike are the best for this type of mission.


This game is a six degrees of freedom shooter inspired by Forsaken and Descent. You must take advantages of your zero gravity bike to solve and complete the levels. Start with a simple laser and grab more weapons to become a real war machine! Translations available in English and French!


The game supports 4 types of HMD

  1. OSVR HMDs*
  2. Oculus Rift DK2 / CV1 (Oculus Runtime 0.8+)
  3. Google Cardboard (with a strap of course)
  4. Gear VR (Soon on the Oculus Store)

In all case it's a plug and play feature, just plug your HMD to your computer and start the game. On Android, you have to enable this feature by yourself.

About Open Source VR (Aka OSVR)

OSVR Support is still in beta stage, you can expect to see regular updates of the game while the support is not 100% bulletproof!

If your HMD crashes when a scene is loaded, unplug your beltbox for 10 sec, plug it again and all will be fine again.

For now Windows x86 / x64 and Linux x64 are supported. You can easily add support on Linux x86 by copying the osvr .so libraries into the Data/Plugins/x86 folter of the game.

The source code is not available for sale, the APK is the full game for Android. Note that it's not updated, the latest version is only available for PC. I'll update the Android port later next month.

The game is made with Unity and the latest version uses the latest OSVR-Unity SDK.

What do you want to do? This game is here for players only. If you want extra licence or anything else, please contact me by mail.
