"After unzipping, the maps are 20MB and 17MB, which makes them the two largest ONS maps (if anyone really cares).
Edit: And by largest I mean in terms of MB, just to clarify."
Although the maps are larger than the small ONS maps that shipped with UT2k4 such as Primeval and Frostbite, a portion of the filesize of these maps is due to content such as textures being included in the .unr (map) file itself. The Unreal engine supports storing data such as static meshes and textures within the level itself, thus helping to reduce the number of dependent files that need to be installed (and thus possibly over-written with earlier/later/incorrect versions or just straight-out lost).
