Hellblade: Senua's Sacrifice

This achievement is story-related and cannot be missed.

As you progress through the game, you will eventually try to pull Gramr out of the Tree but fail in your attempt. You will then be presented with four challenges: Blindness Shard, Tower Shard, Swamp Shard, and Labyrinth Shard.

At this time, you can enter each challenge individually by approaching one of the four blue runestones on the surrounding shore and focusing on it. The achievement will unlock once you have completed the Swamp Shard Challenge.
