A-50

A-60 is one of the Monsters in Rooms. It starts spawning once one player reaches or opens the door to the Room 60. It gives ROOMS veterans PTSD if they hear something resembling a faint buzzing.

Details
A-60 appears as a glowing red entity with a constantly changing face.

A-60 will randomly spawn after the players have passed Room 50, But will only spawn around Room 60. It spawns at A-001 and will start to pursue any players that are currently not in a locker. It emits a static/buzzing noise that has a faint voice mixed in with the buzzing. Said buzzing cannot be heard by Ghosts. If all players are in a locker and a set amount of time has passed it will then despawn.

A-60 will take to time to despawn, and the speed at which it chases the players, increases the more it is encountered. When you hear the static/buzzing noise stop, it means that it has despawned, and that it is safe to leave your locker.

Strategy
A-60 moves at a very quick pace, so take any noise you hear seriously. The buzzing gets louder the closer he is to you, and the buzzing is heard globally so it will not matter turning sideways to hear A-60.

Turning your volume up to a maximum amount will help you hear better, but will be toned out by louder noises such as Gummy Flashlights and metal footsteps. Every time a player opens a room with easily accessible lockers, they should stop and listen for A-60. If you enter a room with metal flooring, sprint through it. Metal floored rooms make your footsteps VERY loud so it is recommended to sprint through metal rooms.

While moving with other players, maintain a two-player group between players as to try and give everyone a chance to claim a locker without being caught out by A-60.

Ghost players might want to stay behind as to spot A-60 when it spawns and alert living players that they're coming. This, of course, will not work if using the in-game chat system, as ROOMS does not log any chat messages, and chat messages can only be read by looking at the speech bubble on top of the player who sent the message.

Another strategy is to press shift + F3. This will bring up your ping and other stats. When your ping starts to rise it means the monster has spawned and is chasing.

Trivia
One of A-60 's faces is the same as the sprite of Giygas from EarthBound.

A-60 was previously thought to have spawned from room 50 and on, being called A-50
