Defend the Terra Attack on the Red UFO
保卫地球：攻击红色UFO
Defend the Terra Attack on the Red UFO is a 1981 arcade action game developed by Artic. Players control a ground-based cannon tasked with shooting down waves of descending red UFOs before they reach the planet's surface. The gameplay shares structural similarities with Space Invaders, placing the player in a fixed defensive position while enemies advance from above. The cannon moves horizontally across the bottom of the screen, and players must time shots carefully to intercept UFOs traveling in formation. Shields or barriers may provide temporary cover against enemy fire. Waves increase in speed and density as the player progresses, raising the difficulty steadily. The game's straightforward shooting mechanics and escalating challenge made it a typical entry in the fixed-shooter genre that dominated arcades during this era.
