The underground is filling up with new things… and we’re eager to keep track of them. We put together this Deadly Delivery update guide to cover every time the game gets additional stuff, so you don’t get too surprised each time a new monster strolls around the corner.
You can play Deadly Delivery over on Roblox. If you’re interested in some of the content, we always have a Deadly Delivery classes guide, and a Deadly Delivery monsters guide.
