UDP Game Protocol
From ASSS Wiki
This is a document outlining the UDP protocol used by game clients (Continuum, SubSpace, and all of the Bots in use today). This is not exhaustive but has been compiled from LogicBot++, MERVBot, and various files from Catid Inside and Snrrrub's Dump. The posted outline is taken from the FPL at Explody's Loot. All clients also use the core protocol. It is, as of right now, incomplete. Some packets do not have their contents filled out.
