SUPERSAD Game-Server is coded in C# using System.Net.Sockets. It act as a authoritative server & communication middle-man for SE Party, broadcasting packets from a client to multiple clients as long as they are connected and related in the game. It also act as a bridge between the client and the underlying database. It also contain multiple state for user of the client such as Lobby/Room/Game as user are only allowed certain action at certain stage of the game.

Packets are transmitted from one end of the protocol to another end. Packets received by the server are prefixed with a Cmd indicating that it is a command sent from a client, while packets sent by the server are postfixed with Ack to indicate that an acknowledgement from the server is received and a response is given back to the client. In order to streamline the process of creating packets that both the front-end client and back-end server development team uses, we maintain a shared logs of packets opscode and packets structures. Packets are generally bytes of data that are packed in a way that the receiving ends know how to process and what to read it for.
