Comet Courier

Earth has picked up a signal from beyond the centre of the galaxy. You fly the fastest courier ship we have, carrying humanity's reply. Your route runs past the planets, through a wormhole, across the Milky Way's most famous landmarks, and onto the photon ring of the black hole Sagittarius A*.

Comet Courier is a free 3D endless runner that plays in your browser on a computer, tablet or phone. There is nothing to install and no account to make. Your best score and settings are saved on your device.

How it plays

Fly a 3 × 3 grid

Three lanes and three flight levels. Your ship stays where you put it, so every obstacle is a question of which square is open.

Keep your tank alive

Fuel drains as you fly. Grab fuel cells to refill it. If you run dry, the engine flames out and you have three seconds to reach a cell.

Deliver the message

Ride the photon ring of Sagittarius A*, where light itself orbits the black hole, to deliver the message for a big bonus. Then loop home and go again, faster.

The route

Every sector is a real place, painted in low-poly style: six planets of our solar system, a wormhole, then six landmarks of the Milky Way on the way to the black hole at its heart. Tap any stop to learn about the real thing.

What you'll dodge

Obstacles are things you could plausibly meet in space. Tumbling asteroids and old satellites, long shard asteroids shaped like the interstellar visitor ‘Oumuamua, laser gates, ropes of magnetic plasma, and the docking decks of space stations. Further out, raider gunships paint your square with a targeting beam before they fire. Power-ups help: Warp, Shield, Magnet and a Blaster with twelve shots.
