I recently left Space Engineers running on the title screen while I afk'd and when I came back, the scene playing out in the background included a tank. Not a wheeled assault vehicle like you play in The First Drop, but an honest-to-goodness, old-school tank... with continuous track, aka "Tank treads."
The only thing I can possibly think of is to use chain-links of hinges, but how would you even keep them on the wheels while turning, let alone avoid the wrathful vengeance of Klang?
I know there's some hidden stuff like train tracks in the vanilla game, but how did they make that tracked-vehicle in the video, and is there a playable method to creating such a thing?
