Game UserMessages (Source)
In addition to events, Source games use UserMessages to send messages from the server to clients.
There are two types of UserMesssage: BitStream UserMessages and Protocol Buffer UserMessages. BitStream UserMessage names can be retrieved using the Metamod: Source "meta game" command. However, this will not give you the type and order of the arguments being sent to the client.
Protocol Buffer UserMessages are well-documented in .proto files included in the game SDKs.
