Create any sort of rocket, satellite, space ship build them from scratch with thousands of different parts with easy drag and drop or attach(auto attachment detector) solid fuel or liquid, jet engines or rocket engines.
You can build any kind of spaceship 100% custom but yet with an assist system to tell you the probability of failure on launch.
After designing and completing your rocket or space station you can easily click on launch and see your monster of a rocket in a launch platform and with using a few keys on the keyboard start the engines and have a lift off with passengers on board.
If you fail at launching and exploding mid air or even with an unbalanced spaceship build you might not be able to even launch and as soon as the platform loads on screen it could collapse on it's self and explodes, though nothing to be worried about you can click on menu and return to garage/ assembly facility to modify and fix your mistakes with looking at a statistic and technical log to see what you did wrong.
This game is the most addictive and the work done on the projects is really huge.
There is a free trial (demo) version to try out in a simple mode with a few body parts, fins/engines/fuel tanks/parachute/modules, to warm up and see what an amazing game this is.
Also you can go to file location and find config file then open it with notepad to even change the thrust/drag/gravity/fuel tanks capacity and all the physics of the game.
I hope you enjoy it and resteem upvote or whatever it is people do here :)
