Unreal Tournament 3 uses the Unreal 3 engine. The assets can be opened in UDK, or exported using Umodel,
– Fraps footage will have the “UT3” prefix.
– The game packages have the extensions .upk and .ut3. Both can be opened in UDK (although it may give a few errors).
– Packages are located in “unreal tournament 3\UTGame\CookedPC”.
– While UT3 comes with an Unreal Editor, the editor has not been updated since release. Using UDK is a better option.
