In the first Banned Footage DLC of Resident Evil 7, there’s a secret achievement or trophy that you can get that involves you searching for Dead Rats.
As you are trying to escape from the clutches of Marguerite, you will come across three Dead Rats in the Bedroom DLC. They are quite easy to find and will just require you to investigate around the area that you are in. As soon as you find that third dead rat, an achievement or trophy titled, ‘Ratcatcher’ will pop up.
Here’s how to find them:
Finding the Three Dead Rats
1. You will find the first Dead Rad in the corner of the room between the Untitled Painting B and the bedside clock that moves the bed away when you solve the puzzle. Simply crouch and you will find it.
2. The second Dead Rat is located in the food that Marguerite gives you the second time. When you see a pot of stew with the fork and stove that you can pick up from the tray, use the Fork to taste the pot of stew. Now, get up and walk around the other side of the bed, next to the clock, and examine the pot again. You should be able to check out the dead rat.
3. The last and final Dead Rat can be found on top of the shelves, inside the Storage Room.
