This is a physics sandbox where you can play around with Starbase devices.
You walk or fly around in first or third person to look at and operate all kinds of devices. For example, you can drive a so called Self Propelled Modular Transporter (SPMT) under the booster, lift it up, transport it from the build site to the launch site (at real world scale and distances), pick it up with the launch tower lifting device (a.k.a. chop sticks) and put it on the launch mount.
Then you can do the same for second stage and stack it on top, launch the full stack, do the hot staging maneuver and return first and second stage to launch site and try to catch them with the chop sticks.
All this is simulated with more or less realistic, slightly simplified physics. You can have it fly mostly automatic (in the future hopefully completely automatic) or control everything yourself, if you wan...
