During the recent Just Survive livestream we saw a hint of the new crate in the inventory, during the King of the Kill stream we got to see a lot more of the potential items for this new crate, some of which we saw added during the last Test Server update but some are yet to be added.
We have tentitiveley added the new Wasteland Crate to our item database and will be adding any new items as soon as they are added to the game files, you can see some screenshots of the new items below. There is also hint that this new crate will be available as unlocked versions via marketplace bundles too.
