Galaxy Defender

Galaxy Defender's wave system ensures every playthrough is unique. During each 18-second wave, the system randomly dispatches different enemy compositions, making threats unpredictable. Higher waves mean thicker enemy HP, more frequent spawns, and faster movement. Post-wave boss battles are each round's climax — boss HP scales dramatically with wave number, three attack modes rotate, demanding optimal decisions under pressure. Defeating the boss advances to the next wave with item rewards, starting a new cycle of intensifying challenges.
