The Void -Axis-

(Description pending.)

While this map does replace all data arenas, you can always use a mod menu to access the map.

And the path you need to type up (or copy-paste) is "open /Game/Maps/Axis.umap"

If you use the data arena version, though, all you need to do is trigger a data fight or select the arena in DG.

Installing this is as simple as placing the unzipped file in the 'Paks' folder wherever you have the game installed.
