The infirmary is one of the locked puzzle rooms C-Team will encounter in Zero Time Dilemma. Here’s how to solve it.
Step 1: Pick up the luminol spray on the desk.
Step 2: Pick up the barcode reader lying on the scanner bed.
Step 3: Grab the stethoscope from the lab coat hanging on the wall.
Step 4: Take the syringe found on the leather bed.
Step 5: Use the luminol spray on the lockers. The combinations for each locker will appear on the locker doors. You only have to open the third and fifth lockers from the left. Their combinations are 413 and 275.
Step 6: Solve the cube puzzle in found in locker 413 to get a key card.
Step 7: Use the key card on the CT scanner monitor to activate. Have Carlos, Junpei, and Akane take the CT scan.
Step 8: Use the barcode reader to scan all three of their readings found on the board.
Step 9: Grab the bottle of ink and lug wrench found in the compartment below the readings.
Step 10: Combine the bottle of ink with the syringe.
Step 11: Examine the poster on the wall, and inject the ink at the part where the candle is. There are two more spots on the poster for you to inject the ink into.
Step 12: Use the lug wrench to remove the screws at all four corners of the poster.
Step 13: Use the stethoscope on the glass case to figure out the combination. The combination is: 15, 7, 12.
Step 14: Examine the case full of antidotes to trigger a cutscene.
Congratulations, you’ve managed to seek a way out of the infirmary in Zero Time Dilemma.
