Mauer Der Toten is packed with surprises and secrets; One of these is the hidden bedroom inside Hotel Room 305. Here's everything you need to know about how you can unlock it and access the Robotic Hands and Safe.
How To Open The Hotel Room 305 Bedroom
Running around Hotel Room 305, you might see a walled-off area on the mini-map. This is, as you might imagine, an accessible area. However, there's a boarded-up door in the way. You can see through into the bedroom, but there's no way to just... "Open the door".
Thankfully, there are a few things you can do in order to get inside. Here's everything you need to know.
Step One: Turn on the Power Switch.
Step One (a): Head to East Berlin Streets, following Objective Markers, and the first Tempest (as seen in Outbreak) and collect the Electrical Fuse they drop.
Step One (b): Continue to follow the Objective Markers and turn on the Power Switch. This will then trigger a second Tempest fight which will drop a second Electrical Fuse.
Step Two: Head to Checkpoint Charlie and activate the Pack-A-Punch machine. You will need to kill the first Disciple enemy in order to activate it. This will be marked with an Objective Marker.
Step Three: Use the Pack-A-Punch machine to add Brain Rot to one of your weapons.
Once you've done this, you'll need to head to Hotel Room 305 and trigger Brain Rot on a Zombie. This will automatically target the Barricade over the secret door and open up the rest of Hotel Room 305.
Why Do You Need To Open It?
There are two reasons why you'll need to open the secret door in Hotel Room 305 on Mauer Der Toten.
Firstly, you'll be able to find the Robotic Hands you need to build Klaus inside. They will be stuck around the neck of a corpse on the bed when you get inside. These are a vital part of completing Klaus, who you will need for the Wonder Weapon Side Quest and should play a part in the Main Quest.
Secondly, you'll also need to access the Hotel Room 305 bedroom in order to find the Safe you need to get the CRBR-S. When you've found the three Safe Combination numbers around Mauer Der Toten, you can enter them into the Safe in this room in order to get a free Wonder Weapon!
