Galtanor's Invasion is an invasion gametype made by Michael Wells, it is based on Satore.
UT3 Invasion is made by Rodney Powers.
Frostbyte adapted BattleRPG P3 to work with these. I am now busy integrating his changes into BattleRPG. Galtanor's Invasion is working now, with UT3 Invasion I am still having some problems, but I think those will be solvable.
