Screen Shots

Event Horizon is a 3D game similar to the classic Escape Velocity game from Ambrosia, but Event Horizon has a first-person view style. Basic game play is very similar: you fly around the galaxy in your spaceship, landing on planets to trade goods or get missions, and buy or sell spaceship addons or another spaceship.

Event Horizon is still in development, but it is playable (not quite fun yet). I only post updates when they are working (mostly) on my computer, so nothing should cause harm to your system. Of course, since it's running under OS X, it shouldn't cause any harm, anyway, not having root access!

Minimum Recommended System Requirements: G3 500Mhz, 256MB RAM, 3D graphics card w/ 16 MB. Minimum monitor resolution of 800x600 is required. OS X 10.2+ (Universal Binary).

Archives of the old forums are available at

Here is the official plugin development guide. Since Event Horizon is still under development, items in this may change from release to release. Be warned!

Event Horizon is now open source. Full source code is available on request.

I originally started developing this game in Java several years ago. Needless to say, it didn't work very well. You can see it here: Event Horizon 0.0.0 and laugh.
