About
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!
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!

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?

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!

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?!

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.

So far, I've played for 12 hours, of which probably 7 have been spent building, 3 flying, and 2 crashing. I'm going to have nightmares about wires and buttons. 10/10 Highly recommended if you like waiting half an hour while traveling to the moon, only to realize at the last moment that you don't have time to brake and you're going to have to make the trip all over again. I had to get a master's degree in mechatronics engineering just to make two engines work at the same time; I have never felt more satisfied. According to the game, I'm only at 5% progress and I've already had enough time to dehydrate myself from crying out of frustration. 10/10 There are a lot of different controls; I always mess up 4 times before hitting the key I was actually looking for (I accidentally dismantled the ship with the 3 previous keys). The editor is very comprehensive. You have a lot of parts at your disposal, and little by little you feel how your creations evolve from flying chunks of metal into very useful and complex ships that allow you to travel very comfortably. You have to have a lot of patience to play it. If you don't like building for an hour and flying for two, this is not your game, but if you have some kind of neurodivergence (like mine), you are going to love it. Unfortunately, I don't have friends to play it with, but I am 100% sure that it is at least 10 times more fun with buddies who also have no idea how the game works. If you open the door while flying, you fly right out of the ship. 10/10 A masterpiece of a game.

mon 1er jeu du genre, très difficile mais vraiment très bien, très prenant !
very good
This game makes my brain hurt SOOO GOOOOOOOOD!!!
This game is a ton of fun. But either I don't know what Im doing, which is usually the issue. But the Break Point System lies to me.
Nice
very good game
One of the best space games I have ever played. It is a physics sandbox and you hand build everything (even wiring!) so it takes a second to get used to. But if you love REAL-feeling space sims and building ships and exploring space. this game is for you. It's a little like Kerbal Space program without the in-game money and less content, but it JUST came out. Way more hands-on ship building here though. I played the demo a while back and logged like 200 hours with only the Earth and Moon available lol. Now there's like 12 planets on game launch and more physics and more parts and more challenges. Game is incredible, and there's years of content planned.
It's like LEGO but for STEM professionals. By FAR the best space/physics sandbox game I've played since Kerbal Space Program 1
love this game, its so me..Fred819
