Teardown is a physics sandbox game where you're tasked with completing increasing less legal jobs by any means necessary. Levels are created entirely from voxels, allowing for full destruction via a number of tools and vehicles.
Jobs can range from destroying certain buildings, stealing items, or avoiding detection as dangerous robots roam the streets. You can complete objectives in a number of ways, tearing down walls with a sledgehammer, explosives and more, creating platforms with wooden planks, and setting up escape vehicles ahead of time.
If you're after something more relaxing, then Teardown's Sandbox mode is for you. Free of mission objectives or story, you can make use of your unlocked tools to create mayhem at your own pace. This doesn't just stop at the base set of levels however, as the game also includes full modding support, with new levels and features available via the Steam Workshop.
