terre.space is a free browser game where you defend Earth from Elon Musk's Starlink satellite swarm. Pilot an orbital fighter, shoot down satellites before they crash into the planet and set it ablaze, and mine Bitcoin to buy upgrades. No download, no sign-up — it runs instantly in your browser on desktop and mobile.
Fly with WASD/ZQSD or the arrow keys (or drag on a touchscreen), aim with the mouse, and fire with click or space. Earth has a health bar that burns as satellites hit it. Every satellite you destroy mines a little Bitcoin — reach 1 BTC to win and own the planet. Race the clock: the global leaderboard ranks players by fastest time to 1 BTC.
Beyond the endless satellite swarm, Elon sends bosses: a pair of Cybertruck-flinging Teslas, a giant SpaceX Starship, and at level 20 an enraged chainsaw-wielding Elon that carves chunks off the planet. Satellites orbit under real gravity, swing around Earth, and dive in faster every level — with a full-on onslaught from level 25.
Spend mined Bitcoin in the Orbit Shop: a double then triple shooter, a self-seeking homing-bullet powerup, Sam Altman acting as a satellite-swallowing black hole, and ROCKY who hops between satellites smashing them. Mine 0.1 BTC to unlock pausing and the shop.
