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. Sharing is a core concept in SR2 and it has built-in capability to easily share crafts and saved games with the community. With SimpleRockets 2, it is easy to get started, but advanced players can dig into technical details if they are interested in the math behind rocket engines and orbital mechanics. Included are 17 different challenges to put your creations to the test. This is actual rocket science! 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 pre-built 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 dig deeper into the complexity of rocket science and design your own rocket engines. Choose from the eight available engine types, seven nozzles, and six fuel types. From there you can change engine size, nozzle length, throat radius, and chamber pressure, which allows for endless combinations of engines.

Use interstages to split your craft into multiple stages and 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.FEATURES
