Payload Studios has just released a big new update for their construction sandbox game, TerraTech.

Update 1.3 focuses primarily on the addition of a co-op campaign that allows four friends to build vehicles, scavenge for resources, and take on missions together. You can watch a trailer above.

The update also adds the Hawkeye armor block set, as well as a variety of other tweaks and smaller enhancements. You can read more about the patch here.

TerraTech is available on Windows PC, Mac, Linux (all via Steam), PS4, and Xbox One for $24.99.
