Drag to steer, hold FIRE. Divers swoop out of formation — keep moving!
How to play
Move: drag horizontally on the playfield, or hold ◀ ▶. Fire: hold 🔥 FIRE, or flip AUTO on and just steer.
Destroy the whole formation to clear the wave — each row is a different alien with its own point value and dive style.
⚠️ Watch for divers: aliens peel out of formation and swoop down at you, firing as they dive. Keep moving!
🛸 A glowing mothership crosses the top every ~25 seconds — hit it for a 200-point bonus.
💠 Blown-up aliens sometimes drop power-ups: S spread shot, H shield (absorbs one hit), R rapid fire.
👹 Every 5th wave is a BOSS — a giant alien with an HP bar. It strafes and fires 3-way spreads; killing it pays a big bonus and always drops a power-up.
You have 3 lives. Getting hit blows you up; you respawn with brief invincibility (blinking ship). Enemy bullets are the glowing orange pixels — dodge them.
Each wave gets faster: quicker marching, more divers, faster bullets, tighter formations. Wave-clear bonus: 150 × wave.
About Galaxy Swarm
Galaxy Swarm is a retro space shooter in the arcade tradition: pilot your ship against endless waves of alien swarms, weave through bullet patterns, and chase the high score. Fast, loud, and gloriously old-school — no story, just survival.
Swarm shooters are about positioning, not reflexes alone. Stay near the bottom-center where you have the most escape routes, prioritize killing the shooters first, and learn each wave's pattern — most enemies telegraph their moves if you watch for a second.
Quick tips
Don't hug the corners — you need escape routes in every direction.
Kill the enemies that shoot first; dumb drones can wait.
Small, constant movements beat big panicked dodges.
