Quick answer

Open-source roguelike shooter. Simple to play, no ads, no tracking, offline.

F-Droid repository metadata

A roguelike shooter caught in a loop you were never meant to escape.

Signal acquired. One ship, one pilot, and a crew waiting to be recruited. Fly out into the dark, survive endless waves of asteroids and enemies, and see how far you get before the difficulty catches up with you.

Every run you pick fresh weapons and upgrades. Recruit a crew of pilots, unlock a fleet of ships, and spend your salvage in the black market between runs. And somewhere in all of it, a story hides in plain sight.

Simple to play. Steer with a single finger, and your guns fire on their own. Easy to pick up, hard to put down. Also plays with a controller or keyboard, in portrait or landscape, and on Android TV.

Built with respect for you and your phone:

* Open source. No black boxes. The whole game is open under GPLv3. * Free forever. No price, no in-app purchases, no pay-to-win. * No ads, no tracking. Zero internet permission. It collects nothing, so not one byte ever leaves your phone. * No sensitive permissions. No camera, mic, location, contacts, files or network. * Plays offline. Works with no signal at all. * No accounts. No sign-up, no login, no email. Open it and play.

No game engine: everything is drawn as vectors on a Canvas in pure Kotlin.

What’s new

The balance patch: weapons and passives retuned, using numbers from Astro Loop Lab.

Enemy weapon rework: most of them hit harder than before.

Android TV: now on the TV home screen.

Weapons fire on the beat better, slightly faster than in 1.4.

Ion Orbiters and Frost Ring hit each target once per pass (both nerfed). No more Energy Saw shards.

Fixed: leaving the app while paused no longer restarts the music, and a certain cutscene no longer gets stuck if you hang out south.

How to install

  1. Download the APK from the button at the top of this page.
  2. Allow “Install unknown apps” for your browser or file manager only, not for every app.
  3. Open the downloaded file and confirm the installation.
  4. If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
