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.
Map List Editor - Map Information
Each side of the Map List Editor can be hidden to show a full height panel that displays information about the map you have selected on the otherside.
This panel also lets you give a personal rating or enter a comment for each map. These two settings have a global context and always relate to that map, regardless of Gametype.
