There are a number of settings that can be found for mlg at the moment. there is no "official" mlg settings, but the settings I have uploaded in my fileshare are the ones that are being tested, to my knowledge. Competitive Lockout, Lotus, Station, Haven v5 and more can be downloaded through my fileshare with respective game types, also in the fileshare.
*GT = Dark Restraint
(note: none of these maps nor settings were created, edited, or originally uploaded by me.)
