About
Experience the realism of space!”
This is the ultimate space simulator game, precisely modeling the space and space environment inside the International Space Station (ISS) under the supervision of JAXA. Gravity, inertia, and orbital mechanics based on realistic physical laws await the player in realistic space. Experience firsthand the tension of moving in zero gravity, operating real space equipment, and executing missions.
Features:.
Realistic space design supervised by JAXA
Simulation of physical phenomena in space as close to reality as possible
Interactive environment with faithful reproduction of the ISS interior and attention to detail

ロシア側のモジュールには入れません。プーチン氏n(粛清)
画面解像度の設定がすげー中途半端な事以外は全てが凄い。 Youtubeで宇宙飛行士の野口さんがこのゲームについて解説してる動画があるから、それを観ながらプレイすると更に感動するからおすすめ。
Best one. Real Simulator. Now I am In. Get Real experience...

terrible. this doesn't simulate anything. point less worthless unoptimized. free is too expensive
Cool stuff here
schlechte Grafik und leider nur in Englisch!! mfg Markus90
Initially, I played for about three minutes and the controls are so bad I just closed the game and went to write a negative review even though the "game" is free (they're that bad). You can't write a review unless you've played the game for 5 minutes or more, so I opened it once more. I figured out how to get into first person mode which helped a ton (what even are these ball things?) In that time though, I did really enjoy the ISS and the model is so good that it does deliver in that regard exceedingly well, so it IS worth checking out. That beings said, if this cost even a $1 in its current state my review goes to negative. Pros: -Amazing graphics -Hyper realistic models and textures -Incredibly close to an exact replica of the inside of the ISS (from what I can tell by pictures and video anyway). -The Earth does turn. I was ready to be disappointed with a static Earth image and was pleasantly surprised to see that there IS movement. -You can spacewalk in an astronaut suit. Cons: -The whole control system needs scrapped. Don't even think about using mouse and keyboard. -There's constant movement of the camera object you represent. It's like it's constantly pulled down which makes no sense as even though the ISS does experience about 10% of Earth's gravity, its orbital state puts it in constant free fall so there should be no "pull" at all. -There's no ability to interact with anything (not a huge gripe for me as I just wanted to look around, but others might hope for more). -There's no sound at all. I want to hear the recyclers, fans, etc. that the space station has normally. There's a VR YouTube video that represents the sounds in different areas that's pretty neat and I'd say go check that out instead but the quality of video is pretty poor and pixelated. -2560x1440 is the highest resolution you can use. Ultrawide or custom resolutions are not supported. -Misspellings and probably incorrect translations by dev. Again, not really a huge issue at all, but when there's a "wind" option that affects your ability to move inside the station I have to believe "wind" is supposed to be another word (Pro tip: turn this option all the way down as low as it can go for better movement) Overall, a good little sim/model that could be made great by using simple WADS controls to move forward, left, right, and down, respectively. Spacebar makes you go up, left shift makes you go down. Any 2 other keys increase and decrease the movement speed. Look around with the mouse. All in first-person (you know, like literally every other First person game out there). That's all that's needed. No weird pull. No "wind" option (what even is wind on a space station?). No robot balls floating around. Add some background sound and allow for custom resolutions and it's hard to find fault.
So, where do I even begin? I'm a space nerd myself and play games like Mission ISS and Reentry - A Space Flight Simulator. The ISS itself is alright, but here's the thing! No audio, not all modules are accessible, the controls take some getting used to, and I've never experienced zero G myself, but I can imagine that ventilation on the ISS wouldn't push a person away, otherwise it would have a storm or something. The ISS doesn't orbit the Earth, again, thanks for that. I would much prefer if an indie developer or team ever takes this to heart and builds a full-scale ISS first, then gradually adds the physics, and releases the whole thing as Early Access. That way, step by step, you don't get overwhelmed, but do it properly. Sincerely, NewTrick2D
Looks nice. Controls make no sense - why is there some strange downward force being applied when one expects to be in zero-G? Why must the player control this weird ball robot that behaves in unpredictable ways? A simple free flying spectator mode would have been enough to appreciate the environment more without all the discomfort introduced by the weird player robot.
Great game! Would've been cool to learn about the components by clicking on them for example.
