Space Tactics
太空战术
Space Tactics is a 1981 arcade action game developed by Sega. The player controls a spaceship viewed from a first-person perspective, tasked with defending against waves of enemy spacecraft and missiles. The game uses a large cabinet with a projected starfield display, giving a sense of depth as enemies approach from the distance. Players aim and fire at incoming threats using a joystick and fire button, while managing limited resources against escalating enemy formations. The game progresses through successive attack waves, with enemies increasing in speed and aggression over time. Space Tactics was notable for its use of a special optical display system that created a three-dimensional battlefield effect uncommon in arcade games of its era.
