Build your own spaceship from scratch
Approximately Up is a first-person space construction and exploration game. You start on Earth with a single frame piece and bolt on thousands of components until you have a working ship. The building tools go deep: automated systems, PID controllers, logic circuits, input controllers, sensors, and meters can all be wired to whatever you need. Electric engines, fuel engines, mixed fuels, solar panels, and heat-resistant frames are among the parts you can unlock by finishing missions. Once the ship looks ready, hit launch and see what happens. The game includes a story with around 200 hours of gameplay.
Play with your crew
You can play solo or in online co-op with up to 4 players. In co-op, the group builds complete spaceships, automated systems, logic circuits, and PID controllers together. Every system matters, so a small design mistake becomes a real problem once you leave the station. There is also a Creative world with unrestricted building for making whatever comes to mind.
Missions across 15 planets
The system holds 15 unique planets, each with its own size, gravity, atmosphere, temperature, look, feel, and dynamic soundtrack that changes as you explore. Planet Stations work as checkpoints and garages where you build ships and start missions; once discovered, a station stays unlocked as a launch point. Missions include retrieving a package from a giant tree, cracking a mystic rock with a bomb, fixing a planet's broken ionosphere, finding mystic or radioactive flowers, tracking down ancient mastodons, heating a hexagonal crystal, and diving underwater. Some missions leave a permanent effect on the world.
Before you launch
All flights are first-person, and distances are huge, so ship design matters: some trips take minutes while weak ships turn them into long journeys. Expect problems like a backward-mounted thruster, unconnected cables, or a door with no button.
