How to Access the Scientists’ Stash in the Hydrodynamics Lab
Step 1: Enter the Hydrodynamics Lab
The Hydrodynamics Lab is located in the northeast corner of Zaton. Begin by entering the main building and clearing out the enemies on the first floor. These enemies are standard fare, so bring your weapon of choice and some medkits.
Step 2: Ascend to the Second Floor
Once the first floor is clear, head to the southwest corner of the building to find a stairwell. Use it to ascend to the second floor.
Step 3: Face the Controller
Here’s where things get tricky. You’ll encounter a Controller, a mutant capable of using psi attacks that distort your vision and cause hallucinations. If you have Psi-Block pills, this is the time to use them. However, if you’re out of consumables, don’t panic. Stay aggressive, focus on eliminating the Controller quickly, and avoid letting its attacks overwhelm you.
Step 4: Prepare for Additional Enemies
After defeating the Controller, be prepared for several zombies to appear. These enemies may not be as dangerous as the Controller, but they can still pose a threat if you’re unprepared. Dispatch them quickly to secure the area.
Step 5: Collect the Electronic Collar
Once the room is clear, search the Controller’s body and retrieve the Electronic Collar. This item will automatically add a note titled Collar Tag Text to your PDA.
Step 6: Determine the Code
Open your PDA and navigate to the Collar Tag Text note. You’ll see two sets of numbers: 48 and 24. Combine these numbers to form the code: 4824.
Step 7: Unlock the Scientists’ Stash
Now that you have the code, head to the small building in the southwest corner of the Hydrodynamics Lab. Enter 4824 into the keypad on the door and press the green button. Congratulations you’ve unlocked the stash and can now claim its valuable contents.
