impleRockets 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, saved games, and even planets 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 a 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.
