At the beginning of the Burning Shores DLC for Horizon Forbidden West, Aloy had an eventful landing. In the process, however, she met Seyka and learned that they had common interest in the large tower off in the distance called Starlight Rise.
With Londra's defensive weapon down, the way is clear to investigate Starlight Rise and learn more about what Londra is planning. The second main quest is fairly straight forward, but it does have a tricky puzzle near the end that requires players to do some thorough investigating. This walkthrough will show Horizon Forbidden West players how to complete 'Heaven and Earth'.
This walkthrough contains spoilers, so players should proceed with caution.
Fly to Starlight Rise
Meet up with Seyka and talk to her to trigger a cutscene. Once the cutscene ends, fly toward Starlight Rise. In order to land once at the destination, hold R2 and the Sunwing will go down to the ground.
How to Get Up the Cliff
While exploring the excavation site, players will encounter broken parts of a ladder. In its current state, the ladder is completely unusable. In order to get up the cliff, use the ballista and shoot at the spots between the ladders. This will create a new climbable part that allows both Aloy and Seyka to progress further.
This won't be the last time players have to use a ballista to progress through this quest. Just up ahead, Seyka will need to turn and hold a crank that lifts a nearby ballista up. While Seyka holds the crank, use the ballista to gain access to the ladder that leads inside the ruined building across the bridge. Use the Pullcaster to lift up toward the ladder and proceed onward.
Search the Ruins
Once inside the ruins, begin exploring. Carefully climb down the elevator shaft. In the next room, there is a prototype of an engine that can be examined. Use the terminal to learn more about the prototype. When ready to proceed, pry open the nearby door to enter the next area.
The chamber ahead is divided by a chasm filled with lava. Approach the ballista and Seyka will volunteer to use it. Once the bolt is in place, use the Pullcaster to reach the other side of the chamber. Before proceeding, deal with the Clamberjaws. Once the machines have been destroyed, Seyka will shoot several more bolts that will allow players to go further up toward another ballista.
Use the ballista to create a path up for Seyka. The ballista can also be used to quickly kill the Clamberjaws that attack Seyka soon after as well. Use the ballista to create a path up on the right. Get off the ballista and glide down toward the left. Use the same path that Seyka did to leave this chamber. Pry open the door ahead and climb up a ladder. Follow the waypoint and pick up any audio logs or documents along the way to learn more about Londra before he left Earth.
How to Find the Door Code
Before long, players will come across an impressive hologram display of Earth. On the second floor there is a door that requires a code. In order to get the code for the door, players will need to use the terminal and have Seyka play audio logs. Each audio log has a transcript with one or more numbers highlighted. In order to open the door, enter the following code: 3285.
Examine Londra's living quarters to learn more about his plans. To progress the quest, activate the terminal with a recent recording made by Londra. With the information about the transmitter, the quest will update. Follow the waypoint and leave the room to reach a door that leads outside.
Before looking for the transmitter, kill all the machines in the area. Once it is clear, find the statue and examine the base to trigger a cutscene. Once the cutscene ends, this quest ends and the third main quest will begin.
Horizon Forbidden West is available now on PS4 and PS5. Burning Shores is available exclusively for PS5.
