Beating Purgatory in the Roblox horror game Residence Massacre (developed by MisterGamer_67) requires systematic bunker management, strict noise control, and predictable AI manipulation. Tied to the in-game badge "Purgatory: Escaping was never an option," this challenge tests your ability to juggle generator fuel, power grids, and oxygen levels while avoiding the lethal Abomination.

Players who beat this mode consistently rely on a "no-bed" pathing strategy rather than hiding constantly. By following a structured cycle between ventilation repairs and power grids, you can clear the night on both standard and Blood Moon conditions without relying on RNG.

Pre-Midnight Bunker Setup

Preparation before the creature becomes active dictates your success. Once you spawn in the bunker area, execute these setup steps immediately:

  1. Unlock and Open Every Door: Unlock the main paths and keep all interior doors open. Opening doors during the night wastes time and produces unnecessary noise.
  2. Retrieve the Kitchen Gas Can First: Grab the fuel canister located in the kitchen area immediately. According to verified bunker runs, the kitchen is the most dangerous and difficult room to access safely once the Abomination roams after midnight.
  3. Open Cabinets and Lockers: Search and open storage lockers early so you can quickly loot items like flares later without door-opening animations.
  4. Initial Barricades: Place your early barricades and use the hammer to seal designated entry points before the clock strikes midnight.
  5. Clear the First Ventilation Check: Cycle the ventilation early to ensure you start the night with full oxygen buffers.

Abomination Spawn Timings and Sound Rules

The Abomination does not spawn at a fixed time; its arrival is tied directly to your generator power readout on your tablet:

  • Normal Mode: The Abomination typically spawns when generator power falls to approximately 45%.
  • Blood Moon Mode: The Abomination spawns significantly earlier, around 60% generator power.

Sound discipline is the single most critical survival mechanic in Purgatory. Walking speed creates minimal sound, allowing you to move through corridors without alerting the Abomination even if it is nearby. Running or sprinting, however, creates heavy audio cues that draw the monster straight to your position. Never sprint through hallways unless you are actively escaping a chase or reaching a failing ventilation unit before oxygen runs out.

Managing Power Grids and Ventilation

Surviving Purgatory revolves around maintaining a strict rhythm: clearing one to two power grids per ventilation cycle. Letting the generator run dry drains your oxygen meter, resulting in death via asphyxiation.

Power Grid Handling

  • When a power grid trips, repair it immediately. The wire puzzle is significantly faster to solve on mobile interfaces than on PC, so take extra care on mouse controls to avoid misinputs.
  • At the start of the night, you can safely repair two power grids before the Abomination closes in.
  • For the remainder of the night, limit yourself to repairing one power grid per ventilation break. Attempting more than one grid while the creature is roaming introduces unnecessary risk.

The Ventilation Loop and AI Pathing

After repairing your scheduled power grid, head directly to the ventilation station. Listen closely for footstep audio and heavy breathing:

  • If you hear no footsteps, complete the ventilation cycle immediately.
  • If the Abomination enters to inspect the ventilation area, stay calm and observe its exit pathing.
  • When it turns left: It will usually circle back toward the right shortly after. Wait in position until it passes.
  • When it turns right: This is your clear window to exit. Leave the area at a normal walking pace—do not sprint.

Surviving Chases: Flash Tech and Flares

While proper pathing prevents most encounters, mistakes can happen. You can use default controls (Shift or L3 to sprint, F, X, or Square for your flashlight) and specific survival techniques if cornered:

The Flashlight Bypass Tech

If the Abomination spots you and closes in, you can perform a flash bypass:

  1. Face the creature directly when it gets within striking range.
  2. Toggle your flashlight on to blind it. The flash causes the Abomination to stun for approximately half a second.
  3. During this half-a-second stun window, its hit detection temporarily disables, allowing you to sprint directly through its model and run toward an exit door.

Flare and Bed Evasion

If carrying a flare during a chase:

  1. Deploy the flare to delay the Abomination.
  2. Break line of sight around a doorway and run toward a room with a bed.
  3. Drop the flare near the threshold, close the door, and immediately interact to hide under the bed.
  4. Complete the hiding minigame until the creature breaks aggro and leaves the room.

Frequently Asked Questions

Can I beat Purgatory without hiding under beds?

Yes. Player-verified runs demonstrate that using consistent walking pathing and timing the Abomination’s left/right turns at the ventilation room allows you to beat the mode entirely without hiding under beds, unlocking achievements like Solid Snake in the process.

What should I prioritize if ventilation breaks while I am fixing a power grid?

Always prioritize ventilation. If you hear the ventilation system break or begin failing, abandon the power grid immediately unless you are in the middle of doing it. Running out of oxygen is an instant run-ender.

How much fuel does a gas can provide?

Each gas can interaction restores 30% of the generator's power. Conserving this fuel and securing a final top-off around 5:00 AM ensures you survive through the final stretch to 6:00 AM even if multiple power grids remain offline.
