One-thumb flight
Storm Surges
Fair rankings
How it plays
Move with one thumb, auto-fire wild weapons, and survive the living storm.
Fly with one thumb while six auto-firing weapons do the shooting. Collect gems, draft upgrades, evolve your kit, and fire Relics when a Storm Surge fills the screen. Daily Storm and Open League give every pilot the same starting build, free or Pro.
- One-thumb control — weapons fire themselves
- Six weapons, paired evolutions, passives, and build-changing Catalysts
- Storm Surges, boss caches, tactical Relics, and fair fixed-start rankings

What is inside
Inside Ionstorm.
One thumb, full storm
Touch anywhere and a floating joystick appears under your thumb. Your weapons fire themselves — your only job is to move, survive, and choose what to build.
Build your loadout one level at a time
Every level offers one of three upgrades — new weapons, passive modules, Catalysts, or late-run overdrives. The run you survive with is the loadout you drafted on the fly.
Break the storm. Keep flying.
Face the Collapsar, then rotating bosses that change the pressure. Destroy a boss or outlast it to earn a relic cache. Reach the Collapsar finale, break the storm, and take your build into overtime.
Relics from boss caches
Outlast or defeat a boss, or clear a rift, to earn a cache — choose one Relic to hold. Nova Bomb clears the screen, Aegis Cell shields your hull, Chain Storm chains lightning through clusters, Magnet Surge vacuums every pickup instantly. Your relic bar holds three; tap any slot to fire it.
