Teardown, the fully destructible sandbox heist game, is adding a creative mode. So not only can you knock stuff down, but now you can build things up. You can also create models and objects in-game and save them for future sessions by "painting" with voxels.
The game also has a thriving modding scene right now, so the new content should be good news to modders, as so far, they've only been able to use external tools. We don't have too long to wait, as the new creative mode update will launch on Steam on the 15th of June, 2023.
