An Unreal Tournament 3 map file contains a level used by Unreal Tournament 3, a game developed by Epic Games for Microsoft Windows.
The file stores the map layout and the placement of objects, characters, and other actors used in the level. It can represent an original game level or a custom level designed by a UT3 player.
UnrealEd, the level editor for Unreal Tournament 3, can create and modify these map files. The format is specific to this older game and its Unreal Engine 3 tools.
On Microsoft Windows, open a .ut3 file with UnrealEd to inspect or edit the map. Unreal Tournament 3 can load the file as a playable level when it is installed in the location expected for game maps.
A .ut3 file is not normally converted to another map format. Use UnrealEd to edit and save it as a map for Unreal Tournament 3; exporting individual assets or level data does not create an equivalent playable map in another game.
