NPCs
NPCs (Non Playable Characters) also known as 'bots' are some of the worlds best and most elite mercenaries that have been hired by Mayor George and the rich elites that now live on Salvation Island to protect them and the island from people like you. Not much, if anything at all is known about the history and lives of these elite mercenaries but be warned, they are really well trained and will not hesitate to put a bullet through your head on sight.
You will mostly find NPCs on Sector B a.k.a Salvation Island, but you may encounter them anywhere as they often come to the islands to get supplies. Some survivors also say they have seen them flying around the islands in helicopters killing anyone they see on sight. Perhaps they want to take the islands over or they just do it for fun? Who knows...
