About the Game
Approximately Up is your best chance to experience spaceflight in whatever you and your crew (singleplayer or co-op multiplayer with up to 4 players) can bolt together! Build epic spaceships or barely flying trashcans — it’s entirely up to you. Control your creation from a first-person view right from the deck of your ship. Complete challenging objectives, hunt achievements, face the dangers of space, and collect new components to expand your current spacecraft — or build hundreds of new ones. One is never enough!
Build spaceships!
Everything begins with a single piece of frame and grows into a massive, complex ship built from thousands of components. Create automated systems, experiment with different input controllers, sensors, and meters — connect them to whatever you need, and let the magic (or chaos) happen! Once it looks ready (or not), hit launch and see what happens!
Complete challenging objectives!
Experimental power sources that need to be delivered to a station on another planet — causing unexpected power outages mid-flight? Some strange energy crystal charging up like a ticking time bomb? Or maybe it’s just a massive, ridiculously heavy submarine this time? Can your spaceship handle that?
Explore the new planets!
Is the planet covered in oceans? What’s hiding beneath that thick atmosphere? Can you see the surface through those massive clouds? Everything’s waiting for you to find out! Explore 15 unique planets, each with its own look, feel, and dynamic soundtrack that changes in real time as you explore and make new discoveries!
Blame each other!
Who forgot to connect that cable? Who mounted the thruster backward? Who forgot the solar panels? Or the door-opening button? Is the radar working? How about the batteries? Enjoy the hilarious chaos in co-op multiplayer with up to 4 players — and find out once and for all... WHOSE FAULT WAS IT?!
So how does it works?
You start on Earth and slowly explore a system of 15 planets, each with its own size, gravity, atmosphere, temperature, and challenges that make every world feel different. Most planets have one or more Planet Stations, which work as checkpoints and garages where you can build ships and start new missions. When you land on a station, it unlocks permanently and becomes a new place you can launch from. To reach these planets, you build your own modular spaceships and experiment with different parts - electric engines, fuel engines, mixed fuels, solar panels, heat-resistant frames, and more. By completing missions like delivering components between planets, you earn new ship parts that let you create better and more advanced designs. All flights are fully first-person from inside your craft, and because distances are huge, your ship design really matters - some trips will take only minutes, while others can turn into long journeys if your ship is weak. The whole game is about exploring planets, upgrading your ships, unlocking new stations, and trying to make it to your destination without crashing.
Note: Demo currently supports English only. Additional languages will be available in the full release.

Steam Patch Notes
Official update history
Hey guys! New micro update 1.0.105 is out:
- Fixed being unable to jump on the surface of planets without an atmosphere after recent patch changes.
- Fixed key bindings sometimes not being saved. They now save immediately whenever you edit them instead of only when exiting a seat. Previously, for example, entering a seat, changing a key binding, and then quitting to the Main Menu could cause the change to be lost.
- Fixed the Thermometer.
- Improved close-range collision detection for the Long Range Distance Meter and Distance Meter.
- Fixed missing localization for the new Space Scanner Manual page.
- When picking a block from the Inventory with RMB, the Inventory will now automatically close.
- Added a new block: Space GPS - must be mounted outside the spaceship with at least 60% free space around it to work properly. When placed correctly, it outputs space coordinates relative to the center of the universe (the Sun): distance, longitude, and latitude.
- Added a new block: Massmeter - measures the mass of the spaceship it is mounted on. Its output updates automatically, for example after decoupling.
- Added 1x Space GPS as a reward for the "Tree Lid" mission on Baobara.
- Added 3x Massmeter as a reward for the "Operation Ghostfire" mission on the Moon.
- Added a new manual entry for the Space Scanner.
- Added a new manual entry for Solar Storms, explaining how they work and how to tell when you enter their deadly zone.
- Fixed Delay internal values not being saved to Time Rewind savepoints.
- Fixed the 3D model of Lever Vertical Half.
- Fixed a bug that could sometimes cause the ABCD labels on a Frame Quarter With Ports chain to not match on both ends.
- Fixed a formatting issue with objective rewards showing "+-2 ...".
- Changed the "Round" mode of the Round block so values exactly halfway between two integers are rounded up to the higher integer.
- Removed the ability to jump in space, as jumping could push you away from the spaceship with no way to return.
- Changed the Fuse Box to trigger when the value is GREATER than the specified threshold. Previously, it triggered when the value was greater than or equal to the threshold.
- Updated the description of the "What Happened To Baobab" mission.
- Changed the Baobara Interferencemeter to simply display the distance to the source of interference instead of using a 0-1 value range. Directly showing the distance should be much more intuitive for players.
- Increased the joint strength of all batteries and Dynamo Boxes by 2.4x, allowing them to withstand greater acceleration and survive harder landings.
- Updated the visuals of the Wind Shield and Solar Shield so they are less opaque and obstruct your view less when active.
Hey guys! New update 1.0.100 is out:
- Added Pause and Fast Forward to the Time Controls menu (default: P), alongside Time Rewind.
- Both Pause and Fast Forward work in singleplayer and multiplayer.
- Fast Forward speeds up the entire simulation by 3x. Nothing is skipped or simplified—the whole simulation simply runs faster.
- Because the game has to simulate 3x as much, Fast Forward uses more CPU resources and may reduce FPS.
- Added a blinking sound when you are about to complete an objective, when the required item starts glowing.
- QoL: Right-clicking an item in the inventory list now puts it directly into your hand without needing to assign it to the hotbar first.
- Highlighted the middle line of the Gyro-Line to make the center of the screen easier to see.
- Changed Fullstar/Halfstar into 3 individual stars.
Performance & Simulation:
- Improved overall game performance by around 10%, most noticeable with very large spaceships. In my test case, FPS increased from 126 → 138 in Build Mode and 80 → 87 in Fly Mode.
- Improved simulation determinism.
- Improved player and package depenetration. Packages such as the Tree Lid or Hazard Barrel should no longer glitch out of the spaceship while being moved by hand.
- Fixed movement artifacts that could slowly push you out of a spaceship while it was landed.
- Improved Long Range Distance Meter calculations from float to double precision, which should help detect extremely distant and small planets.
Balance & Gameplay:
- Slightly decreased the strength of solar storms.
- Lowered gravity inside the Black Hole Tunnel by 100.
- Reduced the radiation radius of the Hazard Barrel.
- Simplified Solar Shield absorption. It previously used flux values, which could be confusing; it now works in degrees as expected.
- Changed the tutorial ship to use only one electric circuit instead of multiple. This should prevent new players from being confused when the Radar, Display, and RCS Thrusters shut off after roughly 13 minutes of flight because those two front batteries died.
Fixes:
- Fixed the Seat outline.
- Fixed some components not appearing in the Objectives inventory tab.
- Fixed knobs on some components not having reduced sensitivity while holding Control.
- Fixed incorrect tree colliders at the Moonstep base.
- Fixed the default FOV of the Camera With Zoom and Rotational Telescopic Camera.
- Fixed an integer overflow when placing an extremely large amount of mass in the building area.
- Fixed thruster heat areas being offset by 0.01m, which could cause floating-point precision issues at their edges.
- Fixed the Red Tank description.
- Fixed packages disappearing from the spaceship after a Time Rewind if they were outside the spaceship before the rewind.
- Fixed packages not being able to take out from the spaceship during spacewalks.
- Fixed Wind Shield wind absorption being incorrectly applied to physics.
- Updated the description of the Ducted Fan speed port.
- Changed all integer/float switches to default to Float instead of Integer, since the majority of components output values in the 0–1 range.
- Added labels to Wireless Transmitters
- Added contact areas to the ports on Frame Quarter With Ports, allowing you to attach components directly to them
- Added switches to Camera Overlay inputs to toggle between displaying integer and float values
- Added a switch to Datameter and Large Datameter to toggle between displaying integer and float values
- When unlocking a new manual, a highlighted green tip will now appear in the bottom-left corner of the screen (so you know you have something new to check)
- When unlocking a new objective, a highlighted green tip will now appear in the bottom-left corner of the screen (so you know you have something new to check)
- Fixed the Workshop "Most Popular" sorting filter, page loading, missing results, and improved overall search clarity. Previously, when searching for new results, it often looked like the first page was skipped and pages 2, 3, 4, 5... were loaded instead, causing incorrect-looking results. This should now work properly.
- Fixed incorrectly assigned renderers on Nanoframe Quarter With Ports, which could cause visually connected ports to mismatch.
- Removed the white-noise overlay from monitors when using an unpowered source as the Secondary Input. The Primary Input will still display white noise when unpowered, but if, for example, you connect a Camera Overlay that is turned off as the Secondary Input, it will now simply be ignored instead of displaying white noise over the Primary Input.
- Improved Frame Quarter With Ports — when you connect a cable to a port on one side, the same port will now appear on the opposite side of the entire connected frame chain. Port labels A, B, C, D will also stay consistent and match on both sides.
- Fixed the geometry of the Middle Window.
- Fixed the geometry of the Small Switch, Small Button, and Stick Switch.
- Fixed an incorrect collider on the huge satellite at the Void Watcher base.
- Updated the Medium Fuel Thruster paintable area to match the Small and Large Fuel Thrusters.
- Fixed the description of Wireless Transmitters — their actual range is 2000m, not the previously stated 100m (it was 100m in the Demo).
- Fixed the camera being locked in Cinematic Mode while seated.
- Fixed the Axis Rotometer hitbox
- Fixed the remaining Axis Rotometer issues — it should now work as intended
- Fixed Plasma Cables not being paintable
- Fixed Autohemisphere Solar Panels not returning to their original position after leaving Fly Mode
- Added painting support for cable holders — when you paint a cable, its holder (the small stick connecting it to the nearest frame) will now be painted as well
- Swapped Yaw and Roll on the front panel of the RCS Controller to match the layout of the output ports on the back and reduce confusion
- You can now open the Manual while sitting in a seat
- Added support for inputting negative speed values into the BPS (will be interpreted as absolute value)
- Fixed world names not being displayed when playing with someone using a completely different localization (for example, an English player joining a Russian player's lobby)
- Changed Whiteboard color switching — you can now select a color by clicking on it instead of using the mouse wheel. I believe this feels much more intuitive. The mouse wheel will be reserved for a future update that should add pen size adjustment
- Adjusted Solar Storm strength. Previously, there was a chance to encounter a deadly Solar Storm while traveling from the Moon to Basalt. That route should now be about 99% safe — I still left a very, very, very small chance of burning up just for fun
- Updated the Rock Obsession radar icon from a filled icon to an outlined one for better readability
- Fixed seat binding labels rapidly changing their positions on screen and jumping around
- Fixed compatibility issues with Metal devices
- Fixed the incorrect default keybind for "Pick the component you're looking at into your hand". It was accidentally set to the mouse side button due to a typo (`Mouse3` instead of `Mouse2`). The default is now correctly set to the middle mouse button
- Fixed a typo in the pipe descriptions
- Added more hints for the Drop The Depth Diver and Trial By Thrust objectives
- Fixed the Fuel Analyzer mode knob not being saved in blueprints
- Added options to invert the mouse X and Y axes while seated
- Fixed the Fuse Box being unable to turn back on
- Fixed the Axis Rotometer outputting incorrect values - it now correctly outputs signed values for the local axes
- Fixed the preview of the Large Disposable Battery
- Added credits and a short startup screen
- Added "Objectives Completion: XX%" to the bottom of the Objectives Log, so you can easily track how much of the full game you've completed and get a better idea of the game's overall size
Added customizable hotbar keybinds. You can now rebind the default 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 hotbar keys to anything you prefer.
Fixed the "Logic Gate OR" incorrectly behaving like an AND gate.
Added a message when connecting to a host with a different game version, indicating whether you or the host needs to update the game.
Updated the descriptions and hints for several missions to make them clearer.
Added a note to the options menu explaining that VSync must be turned off before using the Max FPS limit, as VSync takes priority over it.
Moved Aundara a little closer to the Moon (from 115M to 95M).
Added an option to disable the in-game Workshop.
