MapMixer is designed to give you more control over the way you launch and manage your game session in Unreal Tournament 3. It replaces the the game's Main Menu and let's you launch either a quick-offline match or a complete session where every map is specifically customised - or randomised. It's a whole new way to manage your UT3 experience.
MapMixer supports it's own internal Faction System, which is quite separate from the standard Factions in UT3. Using the MapMixer Faction Editor requires no confusing manual ini file editing and it's easy to assign newly downloaded and installed characters to existing or new Factions.
The Faction Editor displays two factions; one on the left and one on the right. This allows you to use drag-and-drop (or buttons) to move Characters between factions very easily. Like the Map List Editor, the Faction Lists support 4 different view modes, so you can decide how you want to view the overall list on screen.
Every time MapMixer detects that a new character has been installed, it automatically adds it to a special Faction called '[Unassigned Characters]', which allows you to quickly see which new characters have been installed and then very easily assign them to a Faction.
