Kerbal Space Program 2

Designing rockets, plotting flights, and exploring celestial bodies give Kerbal Space Program 2 its distinctive appeal. It costs $42.45 from GameBillet; weigh that against your appetite for a spaceflight simulation centered on solo play. Player reviews offer another point of reference before you decide whether this is the right moment to take on its construction and piloting challenges.

The revamped assembly interface, new parts, and maneuver planner suit players who enjoy refining their spacecraft. If that combination of building and navigation is what you want, the offer may fit; otherwise, the next announced Steam sale is another possible buying opportunity, without any guarantee of participation or a discount. The $42.45 offer from GameBillet can be weighed against the next announced Steam sale window, Dec 17, 2026 – Jan 4, 2027.

The game is officially dead, it managed to get one real update before they pulled the plug. Its a real shame, it really is. Now what TakeTwo or whoever owns this IP should do, is remove it from the store, but they probably wont. So hopefully Valve will take it off the store, since the store page is just trying to sell a dead product. Ill leave the review positive, because all the upvotes make me feel better. __________________ Follow my Curator for more! Before You Buy!: A "Review" of Kerbal Space Program 2 Early Access. I will update this review as more content is released. What You Currently Get with Early Access: The Kerbol System: This is the base game system from Kerbal Space Program 1 and is the only system available at the moment. Full Visual Overhaul: This includes the new Kerbol System, clouds and trees, planet rings (although at the moment, we only have one planet with a ring), and a new Kerbal Space Center. New Tutorials: These are designed to help new players learn the game mechanics. (I really like these) Improved Rocket and Plane Building: This is one of the best new features, allowing for customizable parts and coloring. This is a game changer for people who are used to play vanilla Kerbal Space Program. Career Mode and Science Aerothermodynamics (Entry Heating and Heat damage in general.) What Is Missing: Career Mode and Science (This will probably be the first thing to be released.) Added Resource Extraction Asteroids and Comets Aerothermodynamics (Entry Heating and Heat damage in general.) Added Colonies Interstellar Travel: Two new systems have been announced for future release. Robotic Parts (From the Kerbal Space Program 1 Breaking Ground expansion) Interiors and first person view: A lot of interiors are missing along with first person cockpit view. This has been announced to come in the future. Modding Support Steam Workshop Multiplayer (This will probably be the last thing to be released.) Romance mode with Valentina Conclusion: This beta is really only worth it if you're a big fan of Kerbal Space Program and can't wait any longer (like me). However, it comes at a steep price for an early access title and will likely only increase by 10-20 bucks when it leaves early access. Additionally, it's important to note that the game is currently very unoptimized and may not run well on most computers. So unless you meet the minimum requirements and are not too attached to your hard-earned money, I wouldn't recommend buying it just yet. However, If you are a very impatient person like myself, and you can afford it, then why not just buy it and watch it grow.Show moreShow less

Okay, so. I'll be updating this review ( I hope ). Time Played: 2 hrs First reaction is sticker shock. There are a lot of promises made, and if those features were available right now that price would probably be worth it. At it is, in early access, $50 is asking for quite a bit when we're getting a game that could easily be done in the original game with some mods. Obviously I'm hoping for greatness, but that $50 price at early access is going to make a lot of people walk. Second reaction is the launcher. Private Division, for some reason has a separate launcher that they clearly want us to create yet another login for. This extraneous bit of nonsense never fails to piss me off. Guys, we're launching from Steam, your launcher can tell we launched the game from Steam. I'm guessing that they're hoping to make this extra launcher a mod hub or something? Maybe something to do with multiplayer. Even if true it grinds my gears something fierce. Especially if they're looking to force us to log into this thing to access those features. Third reaction is at the EULA (browse it at take2games.com/eula ). Now, I get that nobody actually reads these complete garbage cans, but I did take a peak at a few terms and WOW is this one ready to throw you to the ground and start at you without lube if you manage to break the terms. First up is all of this will be done using New York legal code, which is kind of famous for all the wrong reasons. Secondly you can expect to see arbitration, not a jury ( that we can wave a right to actual trial like this is still BS ). For those of you who don't know, arbitration is legal code for the company wins because the arbitrator is rewarded ( paid ) for favoring them because the arbitrator will get more cases if they favor the company. I don't expect any of that to actually happen, but it does go to show the prevailing mindset in the developers studio. There is a hefty section on in game currency and purchases, so we may very well be subjected to micro-transactions or other garbage. Modders: you will not be able to make any money from your creations. No surprise, but it goes further. Basically if you create a mod, you do not own it. At all. For those unaware, back in the day there was an RTS game called Warcraft 3. It was immensely popular. One of the reasons for this popularity was the incredible freedom that modders had to create custom maps. Eventually a collection of maps called "Defense of the Ancients" became a significant percentage of all WC3 online games. "Defense of the Ancients" would be so popular that those guys would go on to make a separate game...and LOTS of cash. There's drama and more to the story, but the important bit is that Blizzard ( the makers of WC3 ) were upset they didn't get that money and decided that any mods to their game was theirs and nobody had legal right to any of it. So. TLDR for modding: don't expect to be able to take any code or ideas you create and profit from them. Also in the terms allows for them to spy on you and sell your data. So, you know. There's that. Fourth: the limits of early access. A lot of players will be immensely disappointed to learn that the only game mode available is sandbox, and a limited sandbox at that. Hopefully science and campaign will come soon, but I'm not really a sandbox guy so I'll be waiting for it. And finally, the gameplay. The tutorials were nice. Graphics are better, but hopefully something that can be improved. I'm not really aware of physics engines to comment. Overall, the rocket builder worked nicely. There were a number of small UI improvements that were quite nice all through out the process. Everything was similar enough to the old KSP that adapting wasn't difficult and the improvements were overall just that: improvements. Getting into orbit of the Mun was no trouble, and the UI changes to show where you entered the sphere of influence were great. Two hours play conclusion...I'm really let down. I mean, the long wait time ( years ), ending in an early access release? The sticker shock? The launcher? The EULA? Especially the spying? At present I don't recommend this game. Maybe they will actually deliver on those rather grandiose promises. Maybe. But honestly, I'm tired of paying for a product that spies on me for people to sell my personal information all over the world. I'm just, really tired of it. And people say things like "You don't have to play" or similar, but damn near every digital product has that in the EULA. Damn near every one. And what does that say about the culture of the owners? Of all of these businesses? Not good. It's just not good. The original KSP was so wildly fun because of the freedom. I'm not entirely sure what freedom this EULA and company culture gives us. Time Played: 3.4 hrs Okay, so first things first. I opened up comments earlier today. I had no idea this review would explode, so feel free to comment away. I would also like to mention that I was able to play the game with out setting up an account on the launcher, so there's that. After hearing a lot of complaints about the graphics I did some testing. For reference I have a 12700k CPU, a 3070TI GPU, and 64 GB of DDR5 RAM ( please be kind, I'm an amateur at this ). GPU temperature never peaked beyond 70C with fans at 60%. CPU temperature peaked at 60C with fans around 50%. RAM usage peaked at 19GB. After idling the PC my resting temperature's seem to be about 10-15C below the game running temp. Interestingly the monitor says the GPU load was complete maxed out, same with GPU memory. I fiddled with the settings a fair bit while in high orbit. My FPS was mostly the same around 27 FPS at native 3840x2160 resolution. When I scaled back the settings to the "Low" preset I averaged 33 FPS. Decreasing the resolution allowed me to hit the low 40s FPS. Obviously there is going to have to be some serious optimization for this thing to work. Time Played: 5 hrs Okay, so I've really been playing around with the settings trying to get that FPS. I noticed that the recommended PC requirements was only at 1440p. So I tried that and...it didn't change much. Regardless of what settings and resolution the game tended to average mid 20s FPS. Higher settings and resolution tended to have lower peaks and valleys. Lower resolution would give me a higher "resting" FPS up to the 40s, but when in action it would dip back to 25 or so. Throughout all of this, my log says the GPU was used at capacity, but the fans really didn't start blasting, so there's clearly something going on. The game is playable at 25 FPS, it's just not as enjoyable as it could be. I'm going to give the game a break and keep an eye out for updates. Oh. And to all the haters out there saying this is a cash grab and drop...I'm aiming towards no it's not that. There's a pretty good music score going on and a bunch of small details ( expanding fuel tanks and more ) that would be pretty pointless to put in for a mere cash grab. So for all the ( many ) faults, I'm pretty sure they're not just here for that. Time Played: 6.1 hrs Patch 1 Significant improvements in FPS. I haven't gone through detailed analysis, but there was a giant jump in performance in a few areas. Anytime Kerbin was in view while in orbit the FPS went strait into the dumpster but the Mun was great. Still a number of bugs. I landed on the Mun in my mid stage (landing gears on next stage), so I decided to save before I did anything else. First bug happened after I planted the flag and couldn't move for some reason. Reloading caused me to fall through the ground. So plenty of bugs still. Take away is pretty good for performance improvements. Any changes to the EULA will probably have to wait until final release ( if ever; let's hope ). I'll check in for the next patch.Show moreShow less

I say this with a really heavy heart, BUT: KSP2 is NOT ready for Early Access, not by a long shot! Edit: And likely never will be You are NOT buying a game that's at the level of KSP1, with the promise of more! You are NOT even buying a game that's at the level of the KSP1 beta, with the promise of more! What you are buying; is a game tech demo scam that is, generously, at the level of the KSP1 Alpha 0.16 of around 2012. But that doesn't even matter, because: You are not likely to even get to the point where the missing KSP1 features are going to bother you! Not to put to fine a point on it, but a fitting description for the current level of technical inadequacies on this project causes epistemological problems of sufficient magnitude as to lay a heavier burden upon the logical and semantic resources of the English language than they can reasonably be expected to bear! Performance is beyond abysmal, even on a reasonably high-end system that runs KSP 1 with 200+ Mods incl. Scatterer/Parallax/8k Textures etc. I barely get 25 FPS. The Floor is Literally made of Kraken! (Valentina fell through the Ground on her first EVA) Building a Vessel with one pod, one fuel tank and any more than 4 Engines is an instant Ticket to 10 FPS or less. Physics are very wonky, Orbital parameters jump around wildly upon changing SOI UI is incredibly buggy and often unresponsive (The Part Manager in particular is a Tragedy) Maneuver Nodes & Delta V calculation are so broken that they might as well not be there at all. The game crashed twice in my 50 Minutes with it. Don't even ask me how Bill Kerman died... The game lacks a shocking amount of basic Features & Subsystems right now NO IVA View (which btw. was present even during the early days of KSP1s alpha) NO Heat System (Edit: allegedly hidden away in the options somewhere) NO World Interactions NO Kerbal Skill Levelling ... On a more fundamental and, I want to stress this, subjective Level: Some of the Design Decisions seem questionable: The Pixelated Art-style of the UI is needlessly distracting and feels very out of Place. I have a feeling that in order to make the game easier to learn, a lot of concepts & controls (like for example VAB Symmetry, or VAB vs SPH Layout) have been "simplified" into just one unified solution. This in my view does not appreciably simplify anything, but rather makes for something that is way worse than the analogous KSP1 solutions. While Wings are now procedural (Yay!), this massively needed and welcome simplification for some reason ends right there. Why? Why, for example, have tons and tons of different fuel tanks? Just so you can say there are many more parts now? The procedural fuel tanks Mod for KSP 1 showed us exactly how it's done, why NOT embrace such easy and obvious QOL improvement when the wings themselves are already procedural fuel tanks? again, subjective, but I am not a fan of the overly "plastic" glossy look that everything has now. The perplexing question really becomes this: Why even launch a game that is this broken? Even with all the good will I can muster; how can anyone with a sound state of mind and a reasonable grasp on reality expect a warm reception, given the glaringly obvious, in many ways game-breaking, issues? I really do (EDIT: HAVE NO) hope that the devs can get this game to where it needs to be! However, given what I have seen, and given that the only sensible explanations I can come up with for launching in this state are not exactly reasons for optimism, I got myself a refund! End of Review Answering recurring Comments beyond this point Regarding the Early Access comments Bro, its a early access… So? That's not a get ouf of Jail Free Card! Again, I am not saying it won't get good, in fact i REALLY want it to! Even with early Access Titles, you should never buy just that promise, there needs to be at least something FUN there already! This game needs at least another year of development before we even get into the territory of a playable Beta, likely multiple years on top of that to fulfil its promise, you have no guarantees the Plug won't be pulled long before that. But there is a more unsettling reality to this: This is not a small Indie Developer without any Line of Credit we are talking about here! It's Take 2 Interactive a massive corporate behemoth, with a present Market Cap of more than 17 Billion €, To them KSP2 most certainly is NOT a passion project, It's nothing more than a business decision. Their responsibility lies with their shareholders and not (us) the Fan-base. Consequently, If it's in the interest of the shareholders to cancel this project, say because after more than three years of development there's little to write home about, then the management at Take 2 Interactive has little choice BUT to cancel it, otherwise it opens itself up to lawsuits by Investors. So NO, people who are unwilling to buy into that future promise for €50 are not "entitled Millennials" as some would have you think, nor do they lack the mental faculties for understanding "what early Access means" they are quite simply rational actors who come to a (regrettable) conclusion based upon the information presently available to them. Regarding the Pricing comments I honestly believe €50, for a working Beta of what was promised, would actually have been an appropriate prize. Space Sims are a niche genre and the cost of living has gone up everywhere, Developers need to be remunerated for their hard work. But, alas, this is NOT a Working Beta of what was promised. Regarding the Physics Adding on that they've had three years already and at the least their physics aren't even done yet. I wanted to omit this, but looking at the comments, I feel it pertinent to add this back in: The Physics System is definitely different and in a way that actually gives me a lot of hope, because CPU utilization, in my short testing, was really surprisingly low. BUT: Kraken Aside (I think it lives underneath Launchpad 2 btw.) It's currently incredibly bouncy and there is zero structural rigidity to the crafts you build. Here to one feels reminded of the early KSP Alpha, where you were forced to put struts on every single part. You misremember early KSP 1 No I do not, obviously some hyperbole was used in the writing of this admittedly harsh review. BUT:If we endeavour to be objective we must hold a 30+ Person Studio, that is 3 years behind schedule & owned by a multi Billion Dollar Publisher, to a slightly different standard than what was initially little more than a one-man show, working out of a Mexico-City based advertising agency. KSP alpha 0.17 had IVA in 2012, this does not in 2023! That is why I chose that as the reference point for my comparison! Obviously KSP 2 has some features right now that weren't present back then. You only played 95 Hours of KSP1 I used a custom .exe because of x64 and mods for the longest time (Kids these days have no idea how life was before CKAN) In reality, I have several thousand hours in KSP1 and started playing in 2011. You only played x Minutes of KSP2 Yes. I have now refunded this game and will hopefully buy back in once the situation improves. Again I really DO hope that this will be the case because KSP is one of my great gaming loves and for all my criticism there is a lot to be praised here as well.Show moreShow less

With today's announcement that Take-Two has laid off the entirety of Intercept Games (confirmed per Bloomberg), I'll finally write my review, which is something I had held off doing until my last drop of hope evaporated. KSP2's development was not as controversial as many online would have you believe, especially compared to more scandalous ones, but for me it is by far the most disappointed I've ever been with a video game. KSP2 was announced in August of 2019 at Gamescon, slated to release in 2020 by Star Theory Games, formerly known as Uber Entertainment. Wikipedia states: "For various reasons, the release date was pushed back to Q3 2021." This is a really funny sentence to me in 2024, knowing that the early access (EA) release would not be coming until a year and a half after that date. During this time, Take-Two established a new studio under Private Division called Intercept Games, poaching a dozen employees from Star Theory, including creative director Nate Simpson and lead producer Nate Robinson. The game would continue a long string of announced delays with little communication and progress updates in between, foreshadowing what was to come. Finally, in October of 2022, an early access release date of February 24, 2023 was announced. The date was, for once, one Intercept Games would stick to. Along with this announcement came a road map of major features for future updates, which outlined the following: early access, science, colonies, interstellar, exploration, and multiplayer, to be release chronologically over an unrevealed timeline. The hype that had died down over the years was [mostly] restored, and Intercept Games had bitten off more than they could chew. Before I get into the release, I want backtrack a bit and have everyone watch the Cinematic Announcement Trailer that was released 4 years ago: https://www.youtube.com/watch?v=P_nj6wW6Gsc& Who is responsible for this? It is by far the best game trailer I've ever seen. It EMBODIES what players love about Kerbal Space Program: the mystique of other worlds, the scale of space, the clumsiness of Kerbals, and the drive we have to succeed after failure. The latter two quite literally embody the Kerbal way, as anyone from KSP1 who has stranded their loyal astronauts on Duna or straight up murdered them on the launchpad can confirm. If you were involved in any way with this trailer, give yourself a huge pat on the back. It may very well be the only good thing Intercept Games ever accomplished. Two weeks before the early access release, ESA held a preview event where content creators could play the game for a few hours. Many of these content creators recording themselves playing and something seemed, well, off. You can see it in their eyes and the way they talk about the game. The very framework which would support every roadmap feature was not built on solid ground. Two weeks later, early access was released. I recall some buzzing in the discord in the days before release about the frame rate, but Intercept has a history of being proactive with the ban hammer and anyone who commented these things was swiftly removed. Forced positivity was the subterfuge they needed to convince themselves that what was about to release was worth a fraction of the resources that had supposedly been poured into it. To cut a long story short, release day was a complete and utter disaster. Performance was abymsal with many high end systems topping out at 15 FPS, crafts were wonky and not in the "Kerbal" way, anti-aliasing looked jagged, maneuver nodes were busted (if you could even manage to get to space in the first place), no reentry heating, and an unlimited number of other failures all reared their ugly heads. Even the tutorials themselves didn't feel like KSP. Wrap all those mistakes into a $50 price tag and it's not hard to see why KSP2's player count dipped below KSP1 within days of launch. I'm not going to pretend like I stuck it out and spent my time troubleshooting and reporting bugs to make the game better. I did what any sensible person would do and asked Steam for a refund. The period that followed went as you would aspect: poor damage control. Intercept gaslighted their fan base and ruled with an iron first on their forums and Discord server. Nate occasionally posted updates on their forums, filled with so much technical jargon it made reading them a bigger chore than booting up the game itself. Other than that, there was a lot of radio silence. I encourage everyone to give this website a whirl, which displays the scale of our solar system if the Moon was only 1 pixel: https://joshworth.com/dev/pixelspace/pixelspace_solarsystem.html While you're scrolling, imagine each planet is an update given by Nate on the development of KSP2. The analogy works. Trust me. In October of 2023, Nate gave a speech at Space Creator Day, in which he outlined some of KSP2's development problems before announcing the first roadmap update, For Science!, which ended up releasing in December of 2023. Performance had improved throughout 2023, and For Science! would give players objectives to work towards, but many of the release day issues remained unsolved, and many questions were still unanswered, like: How could a planned release date of 2020 be delayed three years into a rushed EA release? Why did you double down on Unity knowing the same limitations would still be there? And ten thousand others you can scour the Internet for in your free time. While you do that, let me end with this final truth: Kerbal Space Program [1] is spectacular. It feels unique, quirky, works, and had tremendous community support. Games in this position are invaluable, and very hard to follow up with worthy successors. Cities: Skylines 2 and Roller Coaster Tycoon World are more recent examples of games that, by and large, failed to recapture any of what made their predecessors unique. Even at its best, which it rarely ever was, KSP2 never felt like KSP1. Sid Meier once said his design philosophy for designing and creating his games is to "play them, over and over, until they are fun." It's clear that Meier's wisdom never carried over to Nate and the KSP2 team, since anyone who played it never had fun. Such is the early access fate, and shame on all of us for buying into it again. No lessons will be learned and will all be stewing in our anger in a few months at the next major letdown. Kerbal Space Program 2 set its sights on the stars. Unfortunately, it sits abandoned at the launch site, having never even taken flight.Show moreShow less
