# MissionFleet: reconstructing the NavyFIELD 2.062 client and server stack

> MissionFleet reconstructs the historical NavyFIELD 2.062 client and server stack using byte-level decompilation evidence and a Rust server implementation. The author reports a byte-matched inventory spanning client and server modules, most of it represented by instruction streams rather than readable C++. Its Rust login transport implements framing, checksums and liveness probes; authentication and the game and save services remain incomplete.
