==Additional Notes==
+
 
+
* Token is unnecessary for a launcher I think.
+
* 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.
+
 
+
==External Links==
+
 
+
* None at the moment.
