Alien Arena
异形竞技场
Alien Arena is an arcade action game developed by Duncan Brown and released in 1985. Players take on waves of invading aliens across multiple stages, controlling a fighter and using it to shoot down enemies before they can breach defenses. The game draws on the fixed-shooter format, where the player moves horizontally along the bottom of the screen and fires upward at descending alien formations. Enemy patterns grow more aggressive as stages progress, increasing in speed and attack frequency. Bonus rounds and power-up opportunities appear between standard combat stages, giving players chances to improve their score or firepower. The controls use a joystick for movement and a single fire button, keeping the mechanics straightforward and accessible for arcade audiences.
