Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Now that we have a solid, fully 3D rocket simulator it's time to get the community involved. We have ideas for key features that we want to implement (such as a Planet Builder and Campaign Mode), but players have great ideas too and we want to include them in the development process and have time to react to those ideas.”

Approximately how long will this game be in Early Access?

“Our goal is to finish Early Access in mid-2019, though we are prepared to change this as we respond to player feedback.”

How is the full version planned to differ from the Early Access version?

“The full version will include more parts, more planets, and modding support. We also plan to add a Planet Builder where players can build their own planets and share them online. Another key feature of the game will be a Campaign mode, which will provide a means of personal progression. At this point, we're not sure exactly what form it will take, but this is one area where we will be relying heavily on feedback from Early Access participants to help mold the final product.”

What is the current state of the Early Access version?

“The game is already a robust 3D rocket and airplane simulator with over 30 parts, multiple planets, several challenges, and much more. Please see the game's description for the complete list of features.”

Will the game be priced differently during and after Early Access?

“We plan to gradually raise the price as we add new content and features.”

How are you planning on involving the Community in your development process?

“Players have great ideas and they're great at finding bugs, so we strive to make it as easy as possible for them to get in touch with us and contribute to the development process.

  • Players can submit their own ideas and upvote and comment on other players' ideas on our Suggestions page.
  • Forums - Steam Forums and the forums on SimpleRockets.com are a great way for players to get in touch with us for troubleshooting issues.
  • Bug Reports - Players can submit bug reports from within the game and include a screenshot and description. The more information they provide the more it will help us to identify and fix the issue.

Dev Notes - 2019.2.18

You may have noticed that things are quieter around here lately. We have shifted our focus over to SimplePlanes so we can finish the 1.8 update. We hope to finish it next month and then we'll return our focus to SR2 development.

Before jumping over to SimplePlanes, Kevin and I made a lot of progress on the new procedural rocket engines. I'm really excited about them and I can't wait to start working on them again. We're trying to make them as flexible as possible to accommodate as much player feedback as we can. Here are some of the options we currently have:

* Engine Type: Liquid, Solid, Nuclear (thermal), Ion
* Power Cycles (Liquid only): Gas Generator, Staged, Pressure-Fed, Electric
* Fuel Types: Kerolox, Hydrolox, Methalox, Solid, Liquid Hydrogen (nuclear thermal engine), Xenon (ion engine)



There are also several nozzle options available. Most of them are fixed geometry, but there is a procedural cone style and a procedural bell style you can adjust to get the exact nozzle area ratio you want. This will allow you to optimize your engine for sea level, vacuum, or anywhere in between. We will also include an altitude-compensating toroidal aerospike nozzle.

Also, Philip did a lot of work to improve support for building airplanes in SR2, including a new option to specify if you are building a rocket or an airplane. Parts will adjust to a more convenient orientation when added and you can also adjust the direction of travel using this new handy gizmo:



In the same aim of improving support for building airplanes, William has been working on adding resizable landing gear. They are still in the early stages of development, but they already show a lot of potential.



We're hoping to get most of this out next month as well, but that will be a tall order! We will do our best!

About This Game


SimpleRockets 2 is a fully 3D space sim that lets you build rockets, airplanes, rovers, or anything you can imagine and explore highly detailed 3D planets. Upload your crafts and sandboxes and share them with the community to earn points. Join us as we enter Early Access and continue adding new features, such as the Planet Builder and Campaign Mode.

We want to make sure we are building a game that players will love, so if you have suggestions for the game, we want to hear them. Those who followed our work on SimplePlanes know that we are highly responsive to player feedback. We are taking this a step further with SR2 and have set up a Roadmap page to open up our development process and be as transparent as possible.





Build crafts by snapping parts together. Choose from the available engines, such as the Mage, which is a powerful kerosene-fueled engine. Or choose the very weak, but highly efficient Ion Engine. Or you can choose both. It's your craft! Nothing will stop you. Use interstages to split your craft into multiple stages to reach incredible altitudes. Piece together modular fairings to protect your precious cargo.

Launch multiple crafts into orbit. You can dock with your existing crafts to build space stations, moon bases, refueling stations, etc. Take photos of your journey across the solar system with the built-in Photo Library tool.





Stretch and shape fuel tanks, wings, cargo bays, fairings, and nose cones with easy-to-use tools that help you create exactly what you want. Resize solar panels, wheels, pistons, shocks, etc to fit your needs. Paint your craft custom colors and tweak their reflectiveness, emissiveness, and texture styles.

Rocket science is hard, so you might run into the occasional, rapid unscheduled disassembly (i.e. explosion). It happens to even the most experienced rocket surgeons. Might as well embrace it and take advantage of the opportunity to snag some spectacular photos.





Orbits are realistically simulated and support time-warp so you don't have to wait several months to reach another planet. The Map View makes it easy to see your orbits and plan future burns, which you can use to set up future encounters with other planets or satellites.

The flight model dynamically updates drag and lift characteristics of your craft as it changes. Re-entry effects kick in when you're screaming through an atmosphere at hypersonic speeds. Be careful, because the excessive heat can cause those aforementioned rapid unplanned disassemblies.



Download from a huge collection of user-uploaded crafts and sandboxes on our website. Upload your own crafts and sandboxes and share them with the community. Rise through the ranks from a white level builder to a gold level builder and beyond.
