PlanetIdle is free to play from a dead rock all the way to a star-gate — that's Chapter 1, the whole of Earth, and it always will be. Chapter 2: Mars is the one paid part of the game: a second, hand-built world you own outright for a single price.

What you get
Chapter 2 carries the whole arc of the game to a second world: a frozen, rust-red desert dragged, storm by storm, toward something that could hold life. It's a full new planet across ten visible stages — the red rock you start on grows before your eyes as your Stardust climbs, all the way to a living world. The last stages stay hidden until you reach them yourself, in your own save.
- A whole new world of art. Every stage of the red world is art-directed on its own — no recolored Earth — with more than a dozen new cosmic structures to build across it.
- A survival layer Earth never had. Dust storms tear at the thin new sky you're building; holding your world together through them — and turning that same weather into power — is the heart of the climb.
- Its own sound. A score and set of effects written for a red-dust world, because survival on Mars shouldn't sound like a blue-ocean dawn.
- A real ending. Like Chapter 1, Mars finishes with a genuine final challenge and a world reborn — not an endless prestige treadmill.
How it works
Checkout opens in a secure overlay right on this page — no redirect, no account to create. The moment your payment goes through, PlanetIdle issues you a license key and applies it automatically in this browser, so Mars unlocks immediately.
