COP DF Flashback (cooperative map) features the 2-Way Teleport System (TTS). TTS teleports single individual players in cooperative games, not groups, not vehicle or non player objects (including enemy AI).
The map works and has been tested by myself and a few others in my server running:
1- Delta Force Extreme II 2- Delta Force Extreme Special Ops Mod 3- Delta Force Extreme VX Mod 4- Delta Force Extreme II Black Ops Mod 5- Joint Ops Advanced Warfare II Mod
Although you can through any version onto servers running the above mentioned games (and the map will work), I labeled everything separately for organizations sake. Plus, I tweaked each specific version a little, but not much.
