A colony is the backbone of many survivors. By joining a colony, you increase your survival rate. By working as one you can get win firefights with raiders, hold off zombies while you forage, and many other things. Unfortunetly, it's not all Good. A large colony often develops rivals, theives , and bombers that ruin all your fun. Some common tools for colonies are the 870mcs (easy to get when there at least 3 of you) the colony gate (easy to make instead of a new gate every 5 minutes) and much more complicated things such as electricity . An example of a colony is the "Survivors" and the "Outsiders". The Survivors are not as violant or not violant at all, unlike the Outsiders.
