Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
Launch into space and operate real spacecraft systems the way astronauts did.
Reentry is a realistic space flight simulator-game that blends authentic spacecraft systems with structured missions, progression, and guided learning, and aims to meet the middle-ground between a simulator and a game.
Create your own astronaut, complete historical and fictional missions, gain experience, and gradually master increasingly sophisticated spacecraft operations.
Spacecraft are extraordinarily advanced machines designed to survive and operate in one of the most hostile environments imaginable. In Reentry you will interact directly with their systems by managing guidance computers, propulsion systems, navigation, life support, and mission procedures.
To support both curious explorers and experienced simulator players, the game provides a full learning environment: the in-game Space Flight Academy, detailed spacecraft manuals, and step-by-step checklists. Reentry gives you the tools to learn these complex vehicles.
Watch the sunrise while orbiting Earth at 25,500 ft/s. Navigate toward the Moon. Monitor the systems that keep you alive while the planet moves beneath you. Feel the solitude and responsibility of being in space.
Reentry is a game about exploration and the experience of operating real spacecraft systems.
Learn the procedures. Master the systems. Complete the missions.
Ready to launch? Welcome to Reentry - A Space Flight Simulator.

In short, this is some of the most genuinely impressive stuff I have seen in my life, but it requires a large time commitment to learn. The time commitment was not a problem for me, as I was glad to learn this kind of thing. I recommend this to people who are not just interested in spaceflight, but systems engineering as well. It is clear that many years of hard work were poured into this simulation (NOT "game". or maybe it is. like 80% simulation 20% game because of the simplifications that were put in. some can, however, be disabled). I have two gripes with this software, however, and they are very fixable: * There is a number of typos in the Academy lessons. * Timescale (specifically 0x/pause) is not available in some scenarios (like launch or when DET is <10sec I believe). I understand speed-ups not being available, but it would be great if 0.5x and 0x could be enabled, especially when I have to go do something urgently in the middle of launch or an external dV burn. Additionally, it requires a solid foundation of orbital mechanics to learn this. I recommend watching some videos or playing a good bit of KSP or SFS (cheaper) for this. Beyond this, the subsystems only go to a certain level of depth, as it would be near impossible to replicate every subsystem in the Apollo, Gemini, and Mercury missions exactly. I don't want these negatives to take away from the insane quality of Reentry. If you really want to go down this rabbit hole, I strongly recommend Reentry. It's at the intersection of history and spaceflight mechanics, and it is excellent. Some of the best money I've spent in my life. Thanks for reading the yap (you probably just scrolled down to the bottom without reading anyway) and BUY THIS!

If you think Kerbal Space Program is fun but not nearly realistic enough, this is the game for you.
When it works, this game is incredible. The graphics are very detailed and even without VR you feel fully immersed into the actual US spacecraft of the 1960's. The author should receive the "Labor of Love" award every year for his sincere commitment to this game. There are some caveats however. First, my original graphics card was overwhelmed and I would get the black screen on my monitor as the GPU temperature soared past 90c. I had to invest in a 5070 card and those are not cheap. But then I had the pleasure of actually entering into and completing the tutorials. Here again is a caveat. Those tutorials are not enough for the steep learning curve you will encounter in the campaigns. Even with the pdf handbooks, I was still having to run the missions several times to learn what to do. No surprise since these spacecraft were, and remain, highly complicated machines. Also, the missions give you a lot of pop-up chatter that does not always help the experience. Learn how to filter these. If you feel you can help with identifying the rough points, the author is extremely dedicated to getting those fixed. No "that's too bad" from him and that remains a plus. By all means invest in the game but be prepared to get to work. This is no time to relax. You are trying to land on the moon. A giant leap for gamerkind.
Космическая программа, но ты Джеб Керман
if all you spaceship centered game developers want to know how to get our attention and make our ships more interesting... THIS is how. Cant count the times ive been in well designed ships and nothing works. Just cosmetic. Having some of this realism in our spaceships would rock. Great game and great educational tool. Well done!!
I was born in the Spring of 1957. I have grainy Zenith B&W TV memories of President John F. Kennedy announcing that the U.S. was going to send humans to the Moon. I followed the space programs of both the U.S. and USSR very closely when I was a [Cold War] kid and into adulthood. I literally started crying when I first saw/heard the trailer for the "Reentry" spaceflight simulation. The detail in this sim is amazing. "Reentry" is going to keep me busy for a while...
So to keep it short, I will only recommend this game if you have an already established interest or at least a slight curiosity towards spacecraft and orbital mechanics. The main game play loop is as follows 1. Do the tutorial [named academy in the game] for each of the 3 spacecraft 2. Do the campaign missions or free play which is just you messing around with the craft 3. Learn more about the spacecraft from posted documentation from the internet or the provided manuals [These are guides about implemented systems in each of the spacecrafts made for this game specifically]. If you really want to learn how to fly Mercury, Gemini, or the Apollo crafts and see SPECE, then yes get this game right now. But if your looking for something simple and easy to pickup or something space related to turn your brain off, then this isnt the game for you. The crafts are VERY in depth and while not exact 1 to 1, they are not easy at all to pick up and take time with a pretty sharp learning curve. But if learning new things related to space exploration, banging your head against a wall, and pressing lots of buttons is drawing you in like it did to me, then its a 10/10.
This is indeed a simulator You'll have to pass plenty of tutorial missions, watch videos, and read dozens and hundreds of pages of provided manuals (including real ones) to properly understand your spacecraft and safely guide it through the mission using minimal or none of in-game assistance. More than 50 hours, but I just recently completed full flight to moon and back, and that's even without a moon landing! There's still plenty of stuff to learn and try including historical missions! Wonderful simulator! Wish developers to continue to carry on with such a great sim with success!
This is quite possibly one of the best, if not the BEST space simulator on the internet, It feels so immersive and the graphics are absolutely beautiful! Every switch and button does something different. One wrong move could kill you. The rockets are historically accurate and very detailed! I have been looking for a game like this for years, and I finally found it. Thank you for making this game! 10/10 would definitely recommend! (you need a decent computer to run this, If you dont have one, turn the graphics down, there are a lot of options for performance!)
Well first of all.... Thank You Petri for your 10 years and counting of invested development, creativity and passion for space flight. This labour of love certainly shows in the most minutest of details even within the menus! I would like to say that this space flight simulator is simply a must for any person with a genuine and serious passion for accurate space flight and procedures. A game this is not (although as Petri points out there is a component that has been "gamified") though generally this is a hardcore simulator and (quoting Petri) "A study level simulator". I could go on about this!.... But I think Re-Entry should speak for itself... allow this simulator to demonstrate how good it is and how much future potential it has.
