MMM is a room based mini-map system which enables maps and mini-maps with rooms that are exposed one at a time.
The kit uses standard Unity conventions to make it extremely easy to use. You can set up a basic room-based mini-map in under a minute.
It includes the ability to mark points of interest like doors and loot and several sample are included.
It includes map saving and loading and multi-scene support (with one map crossing over multiples scenes).
MMM is primarily intended for use in 2D games but can also work with 3D games with a 2D map projection.
