How gusmarcum/fallout2-coop works

Fallout 2 Co-op is a multiplayer game: each player runs a client, while a dedicated server owns and persists the shared world. The main workflow is players joining, sending actions, and receiving updates from that authoritative world. The README documents major gameplay additions, including trading, revival, party-wide XP, quicksave/load, and companion orders. Paths are based on the supplied tree; where source was not sampled, documented features are represented without speculative internal call links.
