The map is one of the most important items to have in Mortal Shell 2, as it allows you to find your way around the shattered world. When you start your game and open the inventory for the first time, you’ll find an option for the map.
To use it, however, you’ll need to unlock it first.
How to get the map in Mortal Shell 2
To obtain the map, you’ll have to clear the initial parts of the game. It took me approximately an hour to reach the stage where you unlock the map, so it doesn’t take too long. The path to follow in the initial stage is pretty linear, so you can’t get lost.

Once you have cleared the initial couple of beacons and made your way deeper into the map, you’ll come across the first mini-boss. You can’t win this fight, and you’re not meant to, either. However, losing the battle doesn’t matter, and you’ll obtain the Harden ability. This is a pretty useful ability that replaces the standard block mechanism for your sword.
Make your way through the room, and you’ll come across a circular area bordering a cliff. This is where you’ll get your first Ova to collect and deposit, as you aim to follow Undermether’s instructions.

Once you collect the Ova, a cutscene will play out. When the cutscene ends, you’ll regain control of your character by a campfire and get a notification that the map has been unlocked.
At first, most areas of the map will be invisible, as you need to explore the spots manually to discover more areas. The map is also really useful when you’re looking to reach a specific spot, as you can create waypoints that act as your guide in the shattered world.
