Enigma 2
谜题2
Enigma 2 is an action arcade game released in 1981, developed by GamePlan under license from Zilec Electronics. Supporting up to two players, the game tasks players with controlling a spacecraft and shooting waves of enemies across multiple stages. Like many fixed-screen shooters of its era, players maneuver their ship horizontally while targeting advancing alien formations. The game builds in difficulty as stages progress, increasing enemy speed and attack patterns. Two players can take turns competing for high scores, a common feature in arcade cabinets of the period. Enigma 2 sits within the space shooter genre popularized by titles like Space Invaders and Galaxian, offering familiar mechanics with its own visual presentation and enemy behavior patterns.
