Cthulhu Saves the World is a role-playing game published and developed by Zeboyd games. In Terror of Dunwitch, the third chapter of the game, the player will explore the city of Dunwitch, a mysterious town full of zombies, and fight Nyarlatothep, a god similar to Cthulhu. October, a young necromancer will also join the team of heroes.

1. Leave the town of Miskatonia and head south. Cross the bridge and continue south. Cross the mountain and the forest, get on the bridge and walk until you find a city divided by a bridge. Enter.
2. The town of Dunwitch is full of undead creatures. The zombies are blocking the way so you have to find a way pass them: go east and enter the house north of your position. Exit through the second door on the right. Head east to enter the graveyard. There is a chest with a zombie tunic for Cthulhu. Take the second exit, enter the church and leave the place to get back on the streets of Dunwitch.
3. If you enter the house on the south-east, you will gain access to the chest surrunded by zombies and get a sharp blade for Sharpe. The bridge that leads to the south part of the town is destroyed so enter the house on your left. Go upstairs to get across the house and exit. Once outside, you will be able to cross the river.
4. Enter the house south of the bridge. Talk to the man inside to buy some equipment then leave. Enter the broken house on your right to get on the other side.
5. Head east and enter the next part of the city. As soon as you change, you will find a youg woman fighting the zombies. October will then join your party. Head south-east and enter the house. Exit through the east wall and enter the next house on your right. Exit and go east to the last house. Exit through the west wall and head north. Cross the bridge and enter the house in front of you. Go upstairs, then downstairs and exit through the west wall. Follow the path between the plants and enter the parking. Go south, cross the bridge and take the other bridge on your right.
6. In the next part of the city, enter the house south of your position and exit. Head north. If you enter the church on your right, you will find a sword for Cthulhu that deal massive damage to the undead. Enter the house in front of you through the wall. Exit the place, and enter the house north-east. Exit through the left door and enter a second time using the second door on the wall. Head east to leave the screen.
7. This is the last part of the city. Go save your game and prepare for a boss fight. Follow the streets until you meet Nyarlathotep.
8. Nyarlathotep is fighting with two zombies. If you defeat them, they will come back to life in the next round so don't bother and focus on the boss. Nyarlathotep is weak to elemental attack. Use fire and make him insane as soon as you can. Heal when needed and keep attacking with Sharpe, October and Cthulhu, only on the boss. Keep Umi as a healer.
9. The city of Dunwitch is now free. Back on the world map, go east and enter the mountain.
