Once Ada gets to the castle in the Resident Evil 4 remake Separate Ways DLC, it’s a veritable puzzle city. Here’s how to solve the shield puzzle in Chapter 4 and get the red ink: right after you just solved another puzzle!
Step 1: Enter the Chapter 4 puzzle room and get the answer key
The answer key is on the desk directly in front of you after you enter the puzzle room: which contains several suits of armor statues and myriad shields on the wall.
Grab it to get a clue as to how you’ll need to approach the room. You can also find it above as a reference cheat sheet.
Step 2: Shoot three shields next to the fireplace in the correct order
Okay, so you actually need to shoot three precise shields that are clumped together in the room: not just any group of shields. Turn left as you’re facing the desk, and look over the fireplace. See that collection of shields? Those are the shields you need, and they’ll actually match up with the cheat sheet.
Shoot the bottom left shield, then the top right shield, then the bottom right shield. The order matters, and you only need to shoot three shields (none of the other ones are factored into this puzzle). You’ll know you have the right shields as they’ll tilt when shot. If the shields do not tilt, you have the wrong wall.
The entire process can be found step-by-step in the gallery above. All you need to do afterward is turn around and grab the red ink out of the drawer. Congrats! Puzzle solved.
