Ionstorm: Horde Survival

Move with one thumb, auto-fire a wild arsenal, crack rifts, and survive a living ion storm that keeps getting meaner.

Hundreds of enemies, one thumb, and weapons that fire themselves. All you have to do is stay alive.

IONSTORM is a horde-survival roguelite built for short, wild runs. Slide your thumb to move through a collapsing orbital battlefield, sweep up glowing XP, and pick one of three upgrades every time you level. Every run turns into a different arsenal: pulse fire, nova bursts, arc lightning, plasma, drones and shields.

THE STORM FIGHTS BACK Enemies get tougher, faster and thicker as the clock climbs. At six minutes The Collapsar arrives, and killing it only brings back a stronger one. A maxed-out early build is not the end of the run; it is where movement, positioning and well-timed relics start to decide things.

IN THE RUN

• Bank panic-button relics from boss caches and fire them when it gets ugly
• Clear drifting rifts for extra control over your next upgrade draft
• Evolve weapons into their upgraded forms

BETWEEN RUNS

• Let the Reactor build up cores while you are away, then claim them
• Spend cores on permanent Forge upgrades for stronger starts
• Play the Daily Storm: one storm, the same seed for every pilot that day

WHAT'S FREE The whole core game. Auto-fire combat, the level-up draft, weapon evolutions, the first Collapsar fight, one official Daily Storm run every day, and the opening tiers of the Reactor and Forge. Deploy runs end at the seven-minute mark.

GO PRO IONSTORM Pro lifts the seven-minute wall for unlimited run time, adds unlimited Daily Storm replays, opens the full Reactor and Forge trees, saves custom loadout presets, and turns on the daily streak and the global survival leaderboard.

No ads, and it plays offline. Survive longer. Draft smarter. Own the storm.
