Settlers focus a lot on repairing and restoring things around the Nexus world. Most of the towns in the game require maintaining, and that’s where the Settlers come in handy. They can also build things in towns like buff stations, vendors, and much more that can be used by other players like Speeders!
Settlers also can build whole new posts around world that can help other players during their time in that area, while at the same time helping yourself. Let’s look at an example. Let’s say you deploy a picnic that grants anyone who uses it a +5 strength buff. For everyone who discovers your picnic and interacts with it you will receive a +2 strength buff. So not only are you helping out other players, but in doing so you are powering yourself up. Or let’s say you find a broken Resurrection Station. Fixing it will help not only you, but other members of your faction in the same area.
