About junon.io

junon.io is a multiplayer space colony survival game inspired by Space Station 13 and Rimworld. You establish a colony, build a space fortress and keep your crew alive by managing oxygen, food and gold. It runs in the browser with no download, so you can start building after choosing a username.

Enemies spawn at night, so the fun comes from planning walls, crafting gear and preparing for raids. You can trade, cook, grow crops and team up with friends using a room code. Players have also made minigames such as Find the Imposter, Bed Wars, Domination and Tower Defense.
