Mirai Senshi: Lios is a turn-based strategy game that takes place on the fictional planet Lios . The kingdom of Cecilia is under attack by the evil Goinkia and his armies. You control Cecilia and her army of robots, who must play through many maps to reach the evil Goinkia.
Along the way, you can visit castles and towns to get helpful advice from the townspeople. When in combat, the game is automatic, as you can only control your actions on the map screen. Your robots have limited ammo and can only be refilled once per turn. If you lose, you'll get another chance; if you win, you'll gain power-ups for your robots. You can also save your game after winning.
