Demon
恶魔
Demon is an action arcade game released in 1982 by Rock-ola. Players pilot a spacecraft navigating through enemy-filled space, shooting down waves of attacking alien forces. The game supports two players, allowing alternating play. Using a joystick and fire button, players maneuver their ship to dodge enemy projectiles while clearing each stage of hostile craft. The difficulty increases as waves become more aggressive and numerous with each successive level. Rock-ola designed Demon with colorful vector-style graphics typical of early 1980s arcade hardware, and the game features distinct enemy attack patterns that require players to adapt their strategies. Scoring is based on enemy eliminations, encouraging players to push for higher totals across multiple runs.
