The 2.1 version of Hypraxis for Mac was available as a free download on our website. The program lies within Games, more precisely Action.
From the developer:
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.
