Starmaster

The starfighter carries laser weapons, shields, and a faster-than-light drive. The fighter also carries a limited energy supply, which is drained by firing the lasers, being hit by enemy fire, warping, or simply flying around. If the ship's energy drops to zero it is destroyed, and the game ends. Enemy fire can knock out the fighter's subsystems (such as weapons) on top of draining energy. The game "universe" is a square-shaped galaxy mapped into a grid of 36 sectors. Each sector can be home to some enemy ships, a starbase, both, or nothing. The player "warps" the fighter to a sector to engage enemy ships; once they are all destroyed, the player moves on to another. The player can also warp to a sector with a starbase, and dock with it (a rather tricky process) to replenish energy and repair damaged subsystems. Enemy ships in turn maneuver through the galaxy as they home in to destroy the starbases. The game is won when all enemy ships are destroyed, or lost if either the player's fighter or all four starbases are destroyed.
