The Death of the Party side quest in Dead Island 2 can be found in Bel-Air by walking down Access Rd. 782.
You’ll hear a man on the intercom asking for help. Interact with the intercom to answer the call. He’s looking for a girl that he accidentally scared away. When you’re ready, head inside the complex to find the girl. Follow the signs for guests pointing to the garden. Once there, take out all the zombies!
Afterwards, speak with Curtis who is on the roof of his house. You can interact with him from the garden. He’ll need you to restore power to his residence so he can operate his chairlift. To do this, head southwest towards the guest restroom. Just before the building (which has a collectible journal inside), take a left and head down the stairs. Follow the path to a small maintenance room. You’ll need a blue water jug to spread the electricity. This jug can be found just outside the door.
Once you’ve restored the power, report back to Curtis. He’ll want you to come inside. Head around the side of his house to reach the front door, taking out the zombies as you go. Go inside the door and interact with the switch on the wall. As he slowly makes his way down the rail, defend him against the wave of zombies. Afterwards, wait for Curtis to sit by the fireplace then speak with him to complete the quest.
As a reward, you’ll receive 1,000 XP and Golf Club. For more guides on Dead Island 2, click here!
