Ionstorm: Horde Survival

No ads. No energy. Just one more flight.

Ionstorm is a one-thumb horde-survival roguelite. Drag to fly while your weapons fire automatically. Collect gems, draft upgrades, and turn a small ship into a storm-clearing build.

BUILD SOMETHING WILD

Combine six weapons, six passives, and five Catalysts. Reroll a bad draw or banish a card from the run. Max a weapon with its paired passive to unlock an evolution that changes how it fights.

OUTLAST THE STORM

Read the warning before a Storm Surge closes in. Face rotating bosses, clear rifts, and earn relic caches. Break the storm in the Collapsar finale, then keep flying into overtime. Store up to three relics, then trigger a shield, a Nova Bomb, or another burst of power when the screen gets crowded.

TWO WAYS TO COMPETE

Daily Storm gives everyone the same seed and starting build, with one ranked flight each UTC day. Open League is the endless board: every league run starts from the same standard loadout, free or Pro, with unlimited attempts, weekly and all-time rankings, and your best survival time on the board. Tap a pilot to inspect the weapons and evolutions they drafted during the run.

GROW BETWEEN FLIGHTS

Your Reactor generates Cores while you are away. Spend them in the Forge to start regular flights stronger. Ranked modes never use the Forge. Upgrade your Reactor, earn Core Shards, and keep building toward your next personal best.

FREE TO KEEP FLYING

Unlimited regular runs, ranked Daily Storm, and Open League are free. There are no ads, energy systems, or forced time limits.

Ionstorm Pro adds every Forge and Reactor upgrade for regular flights, three saved loadout presets, 2× and 3× play speed, and unranked Daily practice. Pro never changes a ranked board: Daily Storm and Open League start every pilot from the same build. A one-time Full Game Unlock covers Ionstorm.
