This side quest has players complete certain puzzles to unlock three secret doors around the map. Each door will give you a reward which can be a weapon, Power-Up, or Silver Bullets.

First Door Puzzle

There are two bookcases, one in the West Balcony and the other in the East Balcony. Each bookcase will have two books that have a symbol on them, you must interact with these four books in a specific order, which is always the same, but which book has a certain symbol will change each game.

The order of the books with symbols you need to activate is the following:

1. Book with a "Q" like symbol on it
2. Book with a "*" like symbol on it
3. Book with a "U" like symbol on it
4. Book with a "n" like symbol with dots on it

If interacted with in this order, the bookcase with the final book will open, revealing your reward.

Second Door Puzzle

Head to the Billiards Room and shoot the pool balls into the pockets in ascending order (1-9). If done correctly, the bookcase in front of the pool table will open up, revealing your reward.

If you get a grenade as the reward, it means you did it wrong and will have to try again next round.

Third Door Puzzle

Head to the Wine Cellar and knife the six barrels that are dripping wine in the order of fastest dripping to slowest. If you knife the correct barrel in the order, a little bit of wine will spurt out of the nozzle.

If done correctly, the bookcase in the intersection of the two areas will open up, revealing your reward.
