Signal → what to do
- A knock and sudden silence mean A-90 has appeared. All the other sounds pause.
- A face flashes in a random spot on-screen—that's a quick warning before the attack. Freeze now, not a second later.
- Red static fills the screen, with a stop sign showing an open palm in the center—the attack is underway. The palm is your clue: stay still.
- You won't hear Screech—A-90 muffles almost all sounds, including important cues from other entities. As soon as the sign disappears, look around.
- All the other entities in the room freeze, giving you a chance to deal with A-90 first.
How to survive A-90: stay completely still
There's one rule: while the stop sign is on-screen, don't move anything. That means no walking, turning the camera, or trying to hide. You can't jump into a closet at the last second, either: the camera jerks when you hide, and that's enough to trigger the attack.
Here's what I do when I hear the knock: 1. I let go of every key. I'm not even embarrassed to take my hand off the mouse. On a phone, I lift my fingers off the screen. 2. I wait for the stop sign to disappear. You can still use Items—A-90 doesn't react to them. 3. As soon as the screen is clear, I look around. Someone else might have approached while the sounds were muted.
There's good news about the network, too. A-90 appears for all players at the same time because the signal goes out to every client at once. High ping doesn't put you at a disadvantage here. If you do flinch, the damage is 90. That's not fatal at full health, but the next mistake could be. So keeping Bandage Packs in The Rooms isn't a luxury: a Bandage Pack can come in handy right after A-90 hits you.
Where you can encounter A-90
A-90 is one of the common threats in The Rooms. The entity returned to the game in the Access Granted Update. A-90 can appear at any time, but you’re most likely to encounter it starting at Room 90. It can show up early, too: it may appear as soon as A-000, or even after you open and enter A-1000.
Its timing is unpredictable. A-90 appears at random, usually every few minutes, and often alongside A-60 or A-120. These joint appearances count separately from regular ones, so A-90 can attack again right afterward. Most often, A-90 appears at the exact moment another entity attacks.
Outside The Rooms, you can encounter A-90 with the Room For More Modifier. It can then appear in The Outdoors and earlier than usual in The Rooms. Modifiers connected to The Rooms returned to the game in the Access Granted Update.
Using a Crucifix against A-90
You can banish A-90 with a Crucifix to earn the Stop Right There badge. When banished, A-90 changes appearance. In my opinion, the only reason to use a Crucifix on it is to get the badge: you can survive A-90 by staying still, and a Crucifix is more useful in The Rooms against something you can't just stand still to avoid.
Modifiers, events, and the Admin Panel
Stop Right There has the same A-90 effect as Room For More, but it keeps A-60 and A-120 out of The Rooms and the regular Floors. With either Modifier, A-90 can attack at the same time as Figure, and in The Library, it can appear alongside Ambush and Screech. In The Greenhouse, Room For More can make Rush appear alongside A-90.
The worst part: A-90 reacts not only to your movements but also to outside movements, so another entity's attack can trigger it. With these Modifiers, attacks from Snare, Screech, Hide, Dupe, and sometimes Glitch can set it off. This kind of double hit can kill you—it depends on your health and which entity attacked. Sometimes A-90 even appears during a cutscene, and then you take damage even if you didn't do anything.
With the Trick or Treat Modifier, the Room For More? effect from Candy summons A-90, which attacks a few moments later. During a cutscene, it doesn't hurt players who stay still. Also, when A-60 or A-120 appears through the Admin Panel, there's a chance A-90 will attack, just like in The Rooms.
What catches players out with A-90
- Jumping into a closet when you hear the knock. The camera movement while hiding triggers the attack.
- Moving the mouse just a little. Any camera turn counts as movement while the stop sign is on-screen.
- Trying to escape A-60 and forgetting about A-90. If both show up, freeze first: A-90 slows A-60 down by half.
- Relaxing after an attack. A joint appearance doesn't replace a regular one, so A-90 can show up again almost right away.
- Going through The Rooms with empty pockets. Without Bandages, every hit just drains your health.
Where A-90 came from and how it became Ransom
A-90 got its name from the room. Starlight says the entity starts attacking after Room A-90, which is where the name comes from. A-90 was created on December 25, 2022, and was called Peter before it got its name in older versions. It has no original version: it only exists in the DOORS version of The Rooms. Originally, A-90 was based on the Photoshop/Omega Flowey monitor and faces from The Living Tombstone's song "Drunk".
A-90 and Ransom: are they the same?
The short answer: in The Archives, A-90 was redesigned and renamed Ransom. Ransom is a revamped version of A-90, and it inherited some of its mechanics.
The difference is big. Ransom doesn't hit you for 90 damage right away. If you moved while it was around, it demands 500 Gold coins. You get 1 minute and 30 seconds to pay. If you don't, you'll take 50 damage and lose all your Items except Ticket and Honey Pot. Another difference: if one player triggers Ransom, the others skip their encounter, while A-90 comes for everyone.
The old bug was fixed as part of the redesign, too. A-90 used to trigger on involuntary movement, including during cutscenes and attack animations. That was fixed for Ransom in older versions. I often get asked, "Was A-90 removed?" No—the original A-90 is still in the game and remains one of the common threats in The Rooms.
A-90, A-60, and A-120 in the same room
In The Rooms, A-90 often doesn't come alone. It sometimes appears when A-60 does. That's when you might be tempted to run to a closet to hide from A-60. Don't. A-90 cuts A-60's speed in half, and if it showed up because of A-60, A-60 will stay slow. In numbers, A-60 moves at 75 studs per second.
Here's the order I keep in mind at every door: freeze when the stop sign appears, then hide from A-60. I used to do it the other way around and lose health every time. The same idea worked with A-120: it's slow enough that it won't kill you while you're standing still for A-90. And that's useful again now: A-120 has returned to The Rooms.
The Stop Right There badge
You get Stop Right There by banishing A-90 with a Crucifix. It's a rare badge. It's hidden and secret, and doesn't count toward progression. Its description says, "Imagine a blue stop sign instead. Simple, right?".
It's clear why it's rare: you have to bring a Crucifix to The Rooms without using it first. There's a theory that the name refers to one of Sans's lines from Undertale unconfirmed.
How things changed over time
- A-90 used to warn you of an attack with quiet static, similar to A-60's sounds in older versions.
- A-90 used to be able to appear at any time, including in the Lobby and at A-1000 in older versions.
- After an A-90 hit, you used to be able to survive one more attack if you restored your health with six Bandages without dying in older versions.
- In The Archives, A-90 was renamed Ransom.
- Its UGC item was also renamed Ransom some time after The Archives Update.
