A real-time Star Trek-style game for the TRS-80.
After you choose your difficulty level (from 1-10), you will be given your assignment: destroy all the Jovian invaders before they eliminate your System Bases (the number of each varies with your difficulty level selection).
Pilot your ship Endever from quadrant to quadrant, hunting down the enemy. Use your long scan to seek them out. Repair and refuel at your System Bases, and respond to their distress calls when they are under attack. Damage is recorded separately for your ship's five systems: masers, deflectors, scanners, hyperdrive, and ion engines.
