The Broken Sky: Walkthrough

In order to get started with The Broken Sky, you'll need to travel to the Memorial Grove, which is far west of Scalding Spear, not far from Tallneck: The Shining Wastes. You'll enter a conversation with Dekka immediately after you arrive, and will then be free to explore the Memorial Grove on your way to speak with Chief Hekarro. Remember to interact with all the consoles for Hologram Datapoints and scan any documents for Text Datapoints. You'll also pick up a Collectables quest on the way. Speak with Chief Hekkaro.

You'll need to travel to Stone Crest to meet up with Kotallo, who'll subsequently lead you to The Bulwark. On the path to The Bulwark, you'll encounter Regalla's rebels, who you can choose to attack head-on or sneak past. Once you're inside The Bulwark, you'll need to formulate a plan in order for The Kulrut to take place. Head down the lift and scan the left-side of the wall. Then use your Focus to highlight a climbing path and scan the ancient generator. Speak with Kotallo and head to a nearby rebel camp.

At the rebel camp, you'll need to fight and kill a Tremortusk. There are Ravager weapons in and around the area which you can use to do damage. The Tremortusk is weak to Frost damage, and it's a good idea to target the weak spot on its underbelly. Loot the cannon from the Tremortusk and take it back to The Bulwark, then focus fire on the ancient generator to bring the wall down.
