Workers are a crucial part of any colony. They are the people who build everything you need.
When the player first starts the game they start with 1 Worker. In order to hire another one you will need a helmet, a tool case and a mallet.
You won't need any workers for recycling, building and upgrading walls or placing decorations.
The maximum un-bannable limit of workers is 5 workers. There are hackers that use more than 5 workers at a time comrades, I suggest you never use their trickery and hacking as it is a sign to yourself and all around you that you are about to get banned by "Luck Norris" the chief and head of Banning in Galaxy Life
