Start by building your base, and placing crystal mines. If your mines are not connected to your base, place a transporter. To defend your base and survive the night, you will need defensive towers.
YORG.io is a game about supply chains and zombies. Your goal is to build a base which survives the night, when zombies attack. Build defensive towers to protect your base. Towers need resources, so you have to build a supply chain using mines and processors. Try to survive as long as possible - can you beat your friends?
