Read full description

Use joints, bones and muscles to build creatures that are only limited by your imagination. Watch how the combination of neural networks and an evolutionary algorithm can enable your creatures to learn and improve at their given tasks all on their own. The tasks include running, jumping, climbing and flying. Can you design the ultimate creature that is good at all of the tasks? The latest update allows you to easily share your simulation saves and creature designs with your friends. Note that this is more of a simulation than a game. There are no real objectives. But there is a lot to learn if you are interested in the basics of machine learning and neural networks. You can even look at the source code if you want. There is also a Mac & PC version available for download and a browser version for you to try out on the main project website (keiwando.com/evolution).

Bring to life anything you can imagine from rockets and airplanes to cars and more. Automate them with a visual programming language. Explore 3D planets and download more from the community. Share your creations online. Complete contracts, conquer milestones, and unlock technology in the newly added Career Mode. AEROSPACE SANDBOX Juno: New Origins is a 3D aerospace sandbox where players can use customizable parts to construct and test rockets, planes, cars, or anything they can imagine in an environment with realistic physics across land, sea, air, and space. CAREER MODE + TECH TREE Take control of your own aerospace company and earn money and tech points as you progress through the game. Complete contracts to earn money, and discover a mixture of hand-crafted and procedural contracts that offer countless hours of new gameplay. Conquer milestones and explore landmarks to earn tech points and unlock new technology in the tech tree. Interactive tutorials are available to show how to build and operate rockets, cars, and airplanes. RESIZE AND RESHAPE PARTS 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, landing gear, pistons, jet engines, etc to fit your needs. Paint your craft custom colors and tweak their reflectiveness, emissiveness, and texture styles. DESIGN ROCKET AND JET ENGINES Engines can be adjusted in a myriad of ways, such as changing the power cycle, combustion pressure, gimbal range, fuel type, and adjusting nozzle performance and visuals. You can customize an engine to be a power house for lift off, or to be a super optimized vacuum engine that maximizes Isp for interplanetary travel. The engine's performance affects its visuals in flight too as shown by the exhaust's expansion or contraction based on its interplay with the atmospheric pressure. Shock diamonds are pretty but they are a symptom of suboptimal engine performance! If you don't care about any of this, then you can just attach a pre-built engine and hit launch! PROGRAM YOUR CRAFTS Easily drag and drop code blocks to program your crafts to log telemetry, automate them, design your own MFD touch screens, etc. With Vizzy, a programming language designed specifically for Juno: New Origins, you can expand the capabilities of your crafts while learning programming, maths, physics, etc. REALISTIC ORBIT SIMULATION 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. DOWNLOAD CRAFTS, SANDBOXES, AND MORE Download from a huge collection of user-uploaded crafts, sandboxes, and planets on SimpleRockets.com. 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.
