There are currently four different adventures in MilMo.

A player gets to choose between Summer Tide Saga and Air World when they first arrive in MilMo straight after The Brink and completing The Horizon.

Players can click the telescope icon at the top right corner of the screen, or press the M key. Then click the compass at the bottom left corner of the map and select an adventure.

It is advised to explore the Summer Tide Saga and The Horizon adventures before visiting any other adventures as it can give you the required experience for the other worlds.

Spooky Island of Mice & Maniax can be unlocked by meeting Bryce in Mushroom Forest, furthermore, to unlock Air World you need to collect 4 Sun Token pieces and go to the top tower at Cannon Island. These tokens are found anywhere on the islands.
