# AscNet: reconstructing a Punishing: Gray Raven server

> AscNet reconstructs a server for Punishing: Gray Raven. Its C# code includes TCP game sessions, HTTP account and configuration endpoints, and handlers for game features. A companion parser reads packet captures, reassembles length-prefixed TCP messages, decrypts them and decodes MessagePack requests, responses and pushes into JSON.
