From the Studio that brought us Space Engineers, we now will get a new game: Medieval Engineers.
(Please note how he builds the Trebuchet)
The game, that should hit Steam Early Access "soon", will borrow some features and ideas from Space Engineers, and the two games will be developed alongside to make them both the best they can. So was the terrain generation of Medieval Engineers already used to create Asteroids for Space Engineers. And Medieval Engineers will probably start with modding support, thanks to the Studios experience with mods in Space Engineers.
