Hypraxis for Mac

From Left Brain Games:

Warlords from the Gygon Starsystem have invaded this sector. You are the last line of defence. Pilot your starship, the Hypraxis, into battle, defeat their hordes and destroy the Gygon cyborg leader, Bauss. Blast asteroids and Gygon starships to reveal Power-Ups. These Power-Ups increase your firepower, add missiles, repair your shields, and provide anti-missile defence. Collect plenty and you will be unbeatable. Take damage and you will lose your firepower. Playing is easy. Point the mouse to where you want to go or what you want to shoot at. Press the shift key to apply thrust. Click the Left Mouse Button to fire.
