In Dead Island 2, surviving the apocalypse in Bel-Air and Beverly Hills means tackling environmental puzzles alongside hordes of undead. One memorable section occurs early in the story during the Room Service for Major Booker main quest, which brings players to the Halperin Hotel. To progress further into the facility, players are tasked with the objective to investigate the hotel pool.
Where to Find the Halperin Hotel Pool Location
The Halperin Hotel is located shortly after leaving Beverly Hills as you follow the primary narrative path. Upon arriving at the hotel premises, players will navigate past various obstacles to reach the central courtyard. The pool area sits right at the heart of this courtyard, impossible to miss due to its glowing green appearance.
When you approach the water, you will notice fumes rising from the surface, indicating high toxicity. Zombies that wander into the water take fast damage and melt away quickly. Before you begin searching for clues, clear out any immediate undead threats nearby to avoid interruptions.
How to Complete the Pool Investigation
To fill the investigation progress bar, you need to examine three key objects surrounding the pool perimeter. The first item is a heavy fluid pump leaking green liquid on the left side near the fountain. Interacting with this pump reveals that a corrosive liquid was being actively circulated.
Next, move toward the far right corner of the pool area to inspect a large container of Caustic-X. This chemical confirms that an industrial alkali was used in vast quantities. Finally, examine the nearby sewer grate where the pump hose leads, showing where the dissolved waste was drained.
Understanding the Story Context and Next Steps
Completing this investigation reveals the dark reality of military actions at the Halperin Hotel. The army utilized Caustic-X to melt large numbers of bodies directly in the pool before flushing the runoff down the municipal drains. Discovering this secret allows the player character to understand what transpired before advancing into the interior rooms.
Once all three clues are logged, a wave of zombies will spawn to attack your position. After defeating the incoming horde, Major Booker contacts you over the hotel intercom with further directions. This moves your mission forward toward room 307 on the upper floors.
