I had 800k+ in career mode from doing contracts with my re-usable jet plane, with only getting to orbit once. I didn't feel like going to the Mun, so I decided to install Infernal Robotics and waste money on developing this: After having around 65k spent on replacing parts destroyed when testing earlier versions, it is possible to have it walk anywhere. If I get better at the controls, that is, as I didn't go further than a dozen meters before messing up the controls and falling over (
).
