The Story

The free islands
are falling

The Ashen Dominion, an industrial junta, has built Storm-class flying fortresses, and it's rolling up the free islands one archipelago at a time.

Stormbreak Squadron, what's left of the carrier Resolute's air wing, is all that stands in the way. Climb into the Kestrel and fly Operation Stormbreak in order, arcade style: from the first patrol over the reef to the Dominion's last command ship in orbit.

Every stage opens with a briefing and closes with a debrief, and ends with the Kestrel landing back aboard the carrier.

“The Ashen Dominion's flying fortresses are taking the free islands. Stormbreak Squadron is all that's left.”

Gameplay

Classic arcade. Made for your thumbs.

A vertical-scrolling shooter in the arcade tradition, with deterministic rules, readable bullets and bosses you take apart piece by piece.

Twin-thumb flying

Built for touch

Twin-thumb flying

Your left thumb fires, rolls and bombs. Your right thumb drags anywhere to steer with a floating stick, so your fingers never cover the Kestrel.

  • Hold FIRE, or turn on auto-fire
  • Floating stick: drag anywhere on the right
  • Pause any time from the top of the screen
Eight levels of firepower

Power-ups

Eight levels of firepower

Every stage starts the Storm Cannon back at power 1, so the power-ups along the way matter. Each level only adds: more barrels, then side spread guns, then heavier rounds. Bombers drop supplies when they go down.

  • PPower +1 cannon power, up to 8
  • SShield Refills your shield cells
  • BBomb One more screen-clearing bomb
  • Losing a life costs one power level
  • Bombs and score carry from stage to stage
Thread the bullet curtain

Roll and bomb

Thread the bullet curtain

A barrel roll gives you a split second of immunity to bullets, so you can roll straight through a fan of fire. When the sky gets too full, drop a bomb and clear the screen.

  • Enemies stay and fight until they're shot down
  • New waves hold while the sky is full
  • A checkpoint before every boss
Weather, light and an orchestra

Living skies

Weather, light and an orchestra

Every theatre has its own lighting, sea, clouds, weather, islands, enemy paint and soundtrack, and every stage its own time of day. Fly through snow over the fjords, sandstorms on the coast and thunderstorms at night.

  • A mission and a boss track for every theatre
  • Dawn, midday, dusk, overcast and night stages
  • 3D aircraft, ocean and destruction

The Campaign

Six theatres. 24 stages. One war.

Each theatre is four stages: three that end with a named stage leader, then the theatre's fortress. Choose a chapter to read its briefings.
