Ray-Thunder — About this game
Ray-Thunder puts you inside a combat machine in a three-dimensional maze. Advance through corridors, use the radar to judge the surrounding area and watch both fuel and damage before committing to another fight. A level can be resolved by finding its control parts or by destroying every enemy robot, giving exploration and combat different routes to the same goal. Choose when to use the standard shot and when a secondary weapon is worth spending. The security system has turned against the city, and restoring control requires knowing where you are as well as firing accurately.
Choose your machine and enter the maze. Toggle radar with SELECT, use short advances to learn the turns and keep track of collected control parts. Watch fuel and damage before chasing another enemy.
