Doors does not end at Room 100. Beyond the elevator at the top of the Hotel lies a hidden sequence that extends the run to Room A-1000 — a brutal, increasingly strange journey through a warped version of the hotel that most players never see. This Doors rooms guide for A-1000 covers how to unlock it, what to expect room by room, and how to survive long enough to see the secret ending.
How to unlock the A-1000 path
Reaching A-1000 requires specific steps at the end of a standard run:
- Complete Room 100 and enter the elevator as normal.
- When the elevator reaches the top, do not exit immediately. Wait inside the elevator car.
- After a short delay (roughly 10–15 seconds) a hidden door or prompt appears — exact mechanic varies by update version.
- Enter the hidden section. The room counter resets to A-1 and climbs toward A-1000.
If the prompt does not appear, you may be on a server where the feature did not load correctly. Rejoin and try again. Some players also report that completing the run solo is more reliable than multiplayer for triggering the sequence.
What changes beyond Room 100
A-1000 is not simply more hotel rooms. The environment shifts noticeably:
| Room range | Environmental changes |
|---|---|
| A-1 to A-100 | Hotel textures, increased darkness, faster entity pace |
| A-101 to A-300 | Colors begin inverting, ambient sounds change |
| A-301 to A-600 | Room geometry becomes irregular, more maze-like |
| A-601 to A-900 | Near-complete darkness, entities behave erratically |
| A-901 to A-1000 | Minimal lighting, high entity density, final stretch |
The difficulty ramps steeply. Entity spawn rates that felt high in the Hotel baseline are multiplied further. Rush and Ambush appear far more frequently, and Screech is almost constant in the dark stretches from A-400 onward.
Key entities and hazards in A-1000
| Entity | Behavior change in A-1000 |
|---|---|
| Rush | Faster travel speed, shorter warning window |
| Ambush | More bounce-backs per encounter (up to 8+) |
| Screech | Near-constant in dark zones A-400+ |
| Eyes | Extremely common in inverted-color rooms |
| Figure | Appears in scripted Library-equivalent sections around A-500 |
| Halt | More frequent in the maze sections A-300+ |
No new entities exclusive to A-1000 have been confirmed, but entity behaviors are more aggressive versions of their standard Hotel counterparts.
Survival strategy room by room
The A-1000 run is too long to detail room by room, but there are strategy phases:
A-1 to A-100 — Treat it like a hard Hotel run. Use the same habits that got you through Floor 1 but assume Rush will come sooner and Ambush will bounce more. Do not waste crucifix charges early.
A-101 to A-300 — Conserve everything. Shop visits are less frequent. Spend knobs only on light sources and healing. The color inversion makes room navigation confusing; move methodically.
A-301 to A-600 — Audio over visuals. In the maze sections, trust your ears over your eyes. Rush, Ambush, and Screech all have distinct audio cues. Keep a light source equipped but rely on sound to detect threats first.
A-601 to A-1000 — Full commitment. At this stage you are likely low on resources. Prioritize closet awareness over items. Know where every closet in each room is before you open the next door. Use your crucifix only for Ambush encounters where multiple bounces make hiding timing nearly impossible.
Grinding this far requires stamina and resources. Keep your account ready for extended sessions — buy Robux before starting an A-1000 attempt.
FAQ
How long does an A-1000 run take?
A full A-1000 completion takes roughly 60 to 90 minutes depending on pace and entity encounters. It is one of the longest single-session challenges in Doors.
Is A-1000 possible solo?
Yes. Many players argue solo A-1000 is easier because the server load is lower and you only need to worry about your own movement. Multiplayer can help with morale but also means entities can track other players into your area.
What reward do you get for completing A-1000?
A-1000 completion unlocks a special badge and, in some versions of the game, unique cosmetics. The reward has changed across updates — check current patch notes for the latest.
Do modifiers apply to the A-1000 run?
If you had modifiers active when you entered the elevator, they carry through to A-1000. Most players advise clearing A-1000 on a clean run first before attempting it with modifier stacks.
Can you save progress during A-1000?
No mid-run saves exist. If you disconnect or the server crashes, the run ends. Stable connection and a fully charged device are important for such a long session.
