Room 404: Don’t Open the Door

It's 3 a.m. at Hanbit Apartments. Ghosts are closing in from both ends of the hallway. Keep the lights on where they matter, power your talismans, and protect the door until 6 a.m.

TEN WAVES. SIX MINUTES.
A full run lasts six minutes. Watch the stairwell and elevator routes, then switch devices on or off as threats approach. Survive until dawn to win. If the door breaks, the night is over.

LIGHT THE WAY, LET THE TALISMANS FIRE
Lights reveal ghosts and slow their approach. Powered talismans automatically attack enemies in range. Face three enemy types: wandering ghosts, light disruptors, and heavy door breakers. Your talismans gain two automatic upgrades as the night progresses.

EVERY DEVICE HAS A COST
Reinforcing the door halves incoming damage, but draws more power. Exceed the safe load for two seconds, or run out of energy, and a four-second blackout shuts down your defenses. Use quiet moments to recharge. Focused charging turns off all defenses and must stay active for at least two seconds.

CHOOSE YOUR NIGHT
First Night reduces damage to the door. Challenge keeps the pressure higher. Pause, adjust the volume, or restart a run whenever you need to.

Painted apartment interiors, a weathered teal door, glowing paper talismans, and three distinct ghost designs set the mood. Play in landscape and tap the device cards or hallway equipment to manage your defenses.
