ROOM 302 (21)

Head to the washroom in ROOM 302 and examine the bloody bathwater.

Use the PRISONER'S SHIRT to soak up the blood.

Read the NOTE FROM THE BLOODY PRISONER'S SHIRT that appears on the shirt. This reveals the location of the basement key and a Sword of Obedience.

Check under your front door for the RED DIARY - JULY 28.

Return through the laundry room.

Retrieve Eileen from her cell on 3F (if left there) or find her red arrow on the map. Minimizing her time alone is recommended.

Head to the second floor and descend the ladder. Wait for Eileen to run around the exterior before entering the cellblock.

In the second floor cellblock, defeat the Twin Victims.

Find the drinks with "black things" (black powder) in the 7 o'clock cell.

Check under the bed in the 7 o'clock cell to find a SWORD OF OBEDIENCE. This specific sword is not required, but you will need to use one shortly.

Optionally, defeat a Twin Victim in the 5 o'clock cell for PISTOL BULLETS and another in the 11 o'clock cell for a HOLY CANDLE.

Ensure Eileen is with you and take the outside ladders down to the first floor. Wait for her to run around the exterior and proceed inside the 1F portal room.

Optionally, explore the first floor cellblock for items like PISTOL BULLETS, a HOLY CANDLE, and a NUTRITION DRINK, while facing Twin Victims and Hummers.

Return to the portal room. Ensure you have the Pistol, a Silver Bullet, and a Sword of Obedience before proceeding to the basement stairway with Eileen.

In the Interior Basement Stairway, if you have read the Prisoner's Shirt memo, a cutscene (a non-interactive cinematic the game plays automatically) will play introducing Andrew DeSalvo (Victim 18).

Defeat Whitestools blocking the path to Andrew DeSalvo.

Prepare for a mandatory fight with Andrew DeSalvo. To defeat him, you must use a Sword of Obedience. A Silver Bullet used in the Pistol is the most effective method.

Warning: If you don't have a Silver Bullet, a Saint Medallion can help slow him down. Holy Candles are also effective; place one or two to keep him in place. Alternatively, use charged attacks with the Rusty Axe or Spade, combined with a Sword of Obedience.

Target Andrew DeSalvo and fire the Silver Bullet into his belly. Then, run up and stab him with a SWORD OF OBEDIENCE to claim the WATER PRISON GENERATOR ROOM KEY.

Warning: Avoid shooting while he is in an animation like standing up, as the Silver Bullet may not register. Wait for him to approach you before firing.

After defeating Andrew DeSalvo, retrieve the WATER PRISON GENERATOR ROOM KEY.

You can fight Andrew DeSalvo in basement 2 for a more open area, but it is not recommended due to time wasted in unreachable areas.
