Senua will wake up wounded. Her blade has been broken, and for the moment she is unable to defend herself. Don't worry, as there aren't any combat sequences in the near vicinity. Continue down the path to encounter a ghost - start following him and use the path between the wrecked ships.
The cave contains a likeness of Senua's mother
You'll descend down to the beach - your hero will regenerate a little and start moving faster. Proceed east to find a cave with a picture of Senua's mother. Continue moving in the direction of the light and use the opportunity to descend to an area that is closer to the ocean. Pick-up the encountered rune and start moving right to discover a footpath and a new story rune.
The coast contains a number of runes that depict the next part of Sigmund's story
Continue beneath the bridge and use the ladder to descend to the floor below. Make an attempt to go around the long ship and continue moving forward. Make your way west to discover a new rune next to the water. Return to the wrecks and continue moving forward - you'll discover a new rune that depicts the next part of Sigmund's story.
Unexpectedly, you'll be taken to a parallel dimension
Start following the ghost encountered next to a large tree. Senua believes that this is the ghost of Dillion, her loved one. Soon, the world will be transformed, beginning a flashback. When everything is back to normal, start moving forward and pick-up a new rune that can be found next to the water.
Turn right to discover the final Sigmund rune. Make your way to the large tree to begin a cut-scene. Senua receives a new task - forging Gramr, a weapon that can take on the gods. You are left with four blue crystals, each leading to special trial that will test your mettle and combat skills.
