CyberStrike Server Specification: DOS client protocol and map format

CyberStrike Server Specification reconstructs the server-facing behavior of the 1994 DOS client of CyberStrike from observation of the client and its printed manual. Four documents describe serial transport, session phases, messages, client rules, server policy, implementation steps and the CBD city-map format so a replacement server can interoperate with the original game.
