Cosmic Ascent

Your satellites orbit a living Earth while raiders dive in from every heading. Hold the line, harness a star, and climb from one fragile world to mastery of a galaxy.

Earth sits alone at the centre of the screen, and they are coming from every direction at once.

Cosmic Ascent is an orbital tower defense about one civilisation's climb up the Kardashev scale. You do not build along a path — you ring a planet with satellites that orbit as it turns, and the enemy arrives from all 360 degrees under real gravity that bends their approach.

Hold long enough and the map itself transforms. Earth becomes a solar system. The solar system becomes five star systems. Then the galactic core stirs, and spacetime starts answering to you.

— THE CLIMB — Ascend from TYPE 0 to TYPE III across a 30-level campaign. Every tier rebuilds the arena, deepens gravity, and grows your reactor. The Sun appears. Planets open for colonisation. A Dyson forge harnesses a star.

— NINE SATELLITES — Railgun, missile, cryo, tesla, lance, graviton, nova, singularity and Dyson collector — each with its own hull, damage type and role. Kinetic, energy and blast all matter, because the enemy fields hulls that punish the wrong choice.

— AN ENEMY WITH A DOCTRINE — Scouts map your guns by dying to them. Wardens shield everything nearby. Menders repair the wounded faster than a loose fleet can finish them. Splitters die into two. Every hull you destroy unlocks its dossier in the codex.

— COLONISE — Claim a world and a settler ship actually flies there. Colonies grow, feed your power grid, pay tithes — and can be besieged and lost, with everything you built on them.

— NO TWO LEVELS THE SAME — Most levels open under a named directive: fewer but far tougher hulls, a browned-out grid that pays double salvage, a bounty run. Waves mutate. Comets pass. Meteor showers cross the arena and thin their lines for you.

— BUILT WITH CARE — A fully generative soundtrack that ascends with your civilisation. Procedural art, from Earth's recognisable continents to each star's limb-darkened photosphere. Haptics on the beats that matter, and full Reduce Motion support.

Free to play, all 30 levels included. An occasional ad appears between runs — one small one-time purchase removes every ad forever. No pay-to-win, no consumable currency, no accounts, and no cross-app tracking.
