Since CC had (and MM has) so many submissions, duplicate icons were/are a common occurance. We would often fix these issues behind the scenes, but sometimes an icon or two would slip between the cracks. This list is ment to give content creators a list of high-quality icons to use, while keeping the overall ammount of icons in MM low. Please try to use these icons first before you start making your own custom icons. Any custom icons not on this list will need to be approved by the judges. We may add additional icons over time if the need arrises.

Current list of accepted maps. If there is a map that you think should be on here, make a post in down below and the judges will review it.
