Sburb is a game where the end goal is to make a new universe for you and some friends to live in.
You automatically start with the Sburb disk but not a computer. To order base items (ie computer, hoodie, ect) you need to go to the Item Catalogue. Go to your inventory, drop your computer down on the ground.
Now you can set your client. The server menu contains the options to drop Cruxtruders, Alchemiters, Totem Lathes, and a punched card.
