In GALALA, endless waves of alien swarms swoop into tight formations before breaking apart to scream toward you in sweeping, curved attack runs. Your mission is to blast through them, weave between their falling bombs, and seize power-ups that grant twin cannons, a piercing laser beam, or mega bombs for clearing the screen. Every third stage culminates in a colossal boss, complete with its own health bar and unique attack patterns. Beware the tractor beam: if it captures your ship, shoot down the captor to escape—and return as a dual fighter, ready to turn the tide.
