About this game

O.R.B.: Off-World Resource Base Overview

The Malus are a product of their planet’s harsh environment. Scarce water, extremely high temperatures, and a volatile climate forged a stout and rigidly disciplined culture based on strength and triumph over adversity. They have come to see themselves as the rightful rulers of the cosmos. The Alyssians are an independent, self-sufficient and fatalistic race, who forsook their individualism for the greater good. They are democratic and egalitarian. However, in an age of scientific progress, those who excel in the military sciences are esteemed above all. Both races will soon discover they are not alone…

O.R.B., the acronym for Off-World Resource Base, is a real-time strategy game that involves the desperate struggle between the forces of two planets for control of the Aldus solar system. You command the military forces of both the Malus and the Alyssians – two radically different races with fundamentally different cultures and motives. Extract resources from asteroid belts throughout several systems to expand and build upon your fleet. Research new technologies to upgrade the capabilities of your existing ships and test your enemies by building new prototypes. Capture enemy ships and steal their technology to open up new research branches.
