Overview
This is the Odamex Launcher protocol, which will help developers develop custom launchers in other programming languages
Transport notes
- This protocol uses UDP (User Datagram Protocol) as its transport medium.
- All packets are uncompressed.
- All data is little endian.

Additional Notes
- Token is unnecessary for a launcher I think.
- First PWAD is always the IWAD
- Game types are: 0 = COOP, 1 = Deathmatch, 2 = Deathmatch 2.0
- Skill levels are: 0 = ITYTD, 1 = HNTR, 2 = HMP, 3 = UV, 4 = NM (Acronyms).
- Player teams are: 0 = None, 1 = Blue, 2 = Red, 3 = Gold
- If CTF is enabled, Teamplay will be enabled and deathmatch (2.0?).
- If Teamplay is enabled, then deathmatch (2.0?) will be too.
- scorelimit, team scores and player teams (excluding team 0) only appear if Teamplay/CTF is enabled.
