Read full description

Starfall Siege is a retro-style arcade shooter built for mobile - fast, frenetic, and endlessly replayable. Pilot your spaceship through dozens of phases across multiple themed worlds and story arcs: frozen tundras, volcanic rifts, digital voids, ancient sanctums, raging storms, and more. Every world ends with a unique boss battle, each with its own attack pattern and pixel-art design. A diverse roster of enemy types stands between you and victory. Face armored invaders, invisible phantoms, erratic berserkers, drone-deploying carriers, mine-laying bombers, and shielded guardians - each requiring a different strategy to defeat. Power up your ship with collectible upgrades: triple shots, piercing lasers, plasma cannons, freeze blasts, shields, magnets, and more. Combine them wisely - the right loadout can mean the difference between survival and destruction. One carefully tuned challenge: 48 phases across 12 worlds that ramp from relaxed to frantic. Fun from the first wave, and beatable once you learn every boss. Unlock spaceships with their own perks and make your pilot yours. Climb the Game Center leaderboard, earn 13 achievements, and discover every enemy, boss, and power-up in the in-game Codex.
