How to play the fourth chapter of Deltarune? As the final chapter of the game, this chapter is different from the previous ones and has a very long process. Therefore, many people get stuck in this chapter and don't know how to proceed, asking how to complete this chapter. To help everyone understand the specific process of this chapter, the following text and image guide for the fourth chapter is provided below. This guide will detail the entire process of the fourth chapter, so after reading it, you will know how to play.

When the game reaches the fourth chapter, the player will appear in a room where Susie and Ralsei will appear and interact with the player. After completing the interaction, they will lead the player into the church, where all the NPCs seen before can be found. A long segment of the story awaits, requiring players to go through the dialogue as required. After completing the dialogue, find all the NPCs in the church and interact with them once more. After completing this, leave the church. Outside, you will see Toriel, and then Asriel will appear to confess his love to her. During this process, Toriel will reject the confession, and both of them will leave.
After they leave, you need to head to the upper right first, passing through the passage there to enter the next map, then go into the shop and talk to the owner. Next, explore the town, talking to all the NPCs again one by one. After completing this, return to Toriel's house for exploration, during which you can level up. After finishing the exploration, return to the school.

Upon arriving at the school, you still need to talk to the NPCs to gather information, then explore and level up again. After that, open the door in front and enter the otherworld. Here, you will meet a younger version of Toriel, and you need to talk to her; she will join your party. With young Toriel, continue exploring. The exploration part is similar to before, involving various mini-games. After completing these, you can go to Toriel's house in the otherworld, enter, and converse with her to progress the story.
After completing the story, exit the house. There will be many NPCs here with whom you need to interact and converse. After that, you can choose to fight them to gain experience or skip it, depending on the player's choice. Then, the Jester will appear, mock the player, and disappear. You need to enter the next map, where you will see a window triggering another story segment. After completing this, enter and see the Jester and other NPCs from the otherworld. Talk to them, and then take the vehicle back to the real world. From there, leave the school and head down, eventually following Noelle to her home, and complete the exploration of her house.

During the exploration, you will see her piano, and you need to interact with it and choose the "yes" option four times. Then, go to the kitchen and interact with the cooking utensils. After completing these, return to the main hall and go to the upper room. Here, you will see a sealed cabinet that needs to be interacted with, leading to a weakened state. In this state, enter the closet, where a dual perspective will appear: one is Noelle's chat perspective, and the other is the player's perspective. Complete the chat in Noelle's perspective, and in the player's battle perspective, collect the hearts, which are hints for the chat. After completing this, Asriel will appear, and you will see an otherworld portal outside. Enter it to meet Toriel, and after talking to her, you will be forcibly teleported out.

Next, use the school's portal to return to the otherworld and find Toriel. She will lead the player into the library maze. Inside, complete multiple battles and navigate out of the library. Upon exiting, you will see stairs that need to be quickly climbed. During this, the stairs will collapse, but after successfully climbing, you will reach the top and encounter the Titan, the boss of the game. Defeat it, and throughout the process, there will be various mini-games to complete. After this, you can return to the original light world, and the otherworld portal will be permanently closed. This is the full process of the fourth chapter.

The above is the full process introduction for the fourth chapter of Deltarune. If you are stuck at any point, after reading the above guide, you should now be clear about the process of completing the fourth chapter. Now that you understand, you can go ahead and experience the fourth chapter yourself.
