Released in 1983, this classic shooter tasks you with defending humanity. Move your battery left and right to intercept UFO bullets and mines. Clear the stage by destroying the target number of enemies—but if you lose your lives or all six cities, it's Game Over.

The battlefield features six global cities—NYC, LON, TKY, MOW, PEK, and PAR—between you and the enemy. This layout creates a dilemma: if you dodge, the city behind you takes the blast. To succeed, stay on the offensive. Aggressive interception to minimize casualties is victory.
