Mystery in the Building Walkthrough

Reach 2F of the Research Center

Make your way to the second floor of the Research Center. Be prepared because calling the lift will summon a group of Landbreakers, so clear them out before boarding.

Open the Crate Behind the Originium Sample

Before you head up, take a moment to explore the rear of the first floor. Tucked behind a large specimen display, you'll find a hidden Crate waiting to be looted.

Go to Yvonne's Laboratory

The moment you step off the lift on the second floor, you'll face another wave of Mutated Landbreakers. Eliminate them, then proceed towards Yvonne's laboratory.

Find Another Way Through

With the main route to the lab blocked, you'll need to detour through the nearby inspection passage. A floating drone will light the way, guiding you through the corridor.

Open the Crate

Keep your eyes peeled halfway through the inspection passage. There's a Crate perched atop a large piece of machinery. You can reach it by jumping down from the nearby elevated walkway.

Defeat the Anomalous Landbreakers

Your progress through the inspection passage will be interrupted by another squad of Mutated Landbreakers. Wipe out all nearby hostiles to secure the area.

Open the Lab Door

With the enemies defeated, the lockdown on the laboratory gate will lift. Open it up and step inside Yvonne's Laboratory.

Look for Yvonne's Other Vinyls

Inside the lab, you'll be tasked with selecting a record for Yvonne. Start by listening to the two records already on the player. Afterwards, locate and play the third record hidden in the corner of the room to trigger the next event.

Defeat the Anomalous Landbreakers

Playing the correct record advances the story, directing you toward the repair platform. Be ready for a fight, as more Mutated Landbreakers will try to block your path.

Go to the Repair Platform

Clear the enemies, open the door, and make your way to the repair platform.

Loot the Crate Inside the Warehouse

On your way to the platform, check the side path leading to a warehouse. You'll find a Crate sitting there, just jump across the cargo containers to claim it.

Defend Tata

Arriving at the repair platform triggers a large-scale ambush by a mob of Landbreakers. Eliminate these grunts to draw out the boss, the Bonekrusha Sniper. Take him down to complete the mission Mystery in the Building.
