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.
There are two ways to launch your game session - which one you choose depends on what you want to do. Use the Quick Session Menu to jump straight into the action quickly, as a standalone match, or use the MapMixer Advanced Session Menu to start a standalone or multiplayer server utilising the full range of customisation and randomisation that MapMixer provides.
Quick Session Menu:
This Menu is divided into three main Tabs - Maps, Rules and Mutators.
Simply select a Gametype and Map, then set your rules and enable some mutators and Play. You could say that this menu is MapMixer's equivalent of the Instant Action Menu. Each time you start a match, it records your settings that you use, per Gametype, so they are there for you next time. Alternatively you can create your own presets to select and recall.
At any point during or after the match you may open this menu from with the current map, using a keybind, in order to launch your next match, so there's no need to return to the Main Menu. MapMixer records these maps in its Session Map List, so you can navigate back to play a match you've already played.
