# PType and PSub Definitions

A BO3 GameServer packet has a 2 byte header.
Byte 1 is PType (packet type), which is used to check whether its serverbound or clientbound, however nonstandard BO3 servers can have the PType above 0x01
Byte 2 is PSub (packet subtype), which is the actual packet name. Each ptype can have 256 different subtypes 

## PType
0x00 = Clientbound (should never be sent by a client)
0x01 = Serverbound (should never be recieved by a client)

## PSub for client

0x02 = Replication channel
0x01 = Echo (Server will return what you send)
0x04 = Recv auth validness
0xFF = kick

## PSub for server
0x03 = Recv auth session
0x02 = Same as client
