How To Upgrade Klaus

There are a total of three upgrades that can be made to Klaus, one of which equips the robot with a Tier 3 Pack-a-Punch weapon so it can deal with any form of undead opposition with ease. For the first upgrade, let Klaus eliminate Zombies around the Garment Factory which is where the Upgrade Station is. Once the small screen on top of the station has turned green, the upgrade can begin.

Guide Klaus into the station where you will have to defend Klaus for 60 seconds. Once the time is up, Klaus will climb out of the station and will wield a Pack-a-Punched weapon.

The next step involves searching a number of electrical boxes that Klaus can use to its advantage. Before beginning this upgrade, make sure to have access to the Blacklight which makes the process much easier. With the Blacklight equipped you'll need to search six electrical boxes. Their locations can be found below:

  • In the corner of the Hotel Lounge.
  • Between a door and a bookshelf inside the 5th Floor Apartments.
  • Inside the Blasted Suite next to the workbench.
  • Under the Cafe Mueller sign in West Berlin Street.
  • Inside the Maintenance Tunnel outside of the Safehouse entrance.
  • Inside the Ghost Station, opposite the entrance to the Maintenance Tunnel.

After you've located the electrical boxes, scan each one with the Blacklight. Two of the six will feature a bright green mark on the wall next to the box. Guide Klaus to the boxes where the robot will punch the boxes to reveal two Cosmetic Disks. Interact with it to store the disk in your inventory and give the other to Klaus.

Head back to the Upgrade Station and enter the disk. Once the upgrade has been completed, Klaus will look like a completely different robot from when you first found him.
