A-200

A-200 is one of the Monsters in Rooms. It starts spawning once one player reaches or opens the door to the Room 200.

Details
A-200 appears as a face that seems to be a white, crude drawing, of a smile.

A-200 randomly spawns at Room 200. When it spawns, the monster A-200 will make a deep bang sound in the ambience, and chase all players not in a locker in the current room. If all players are inside a locker, A-200 will then despawn shortly after. When you hear a ghostly voice echo on the ambience, it means that it has despawned and that it is safe to leave your locker. All of A-200 's sounds can be heard by Ghosts.

Strategy
As soon as the deep bang noise from A-200 is heard, quickly get inside the nearest locker either in the room you're in or in any previous room with a locker inside. Opening another door during its attack might cause you to be jumped and killed by it. However, it's not too hard to avoid A-200 's attack since it is slow, and even if you opened another door during its attack, you can still outrun it in most cases. And if you're inside a locker when the deep bang sound is heard, it almost instantly despawns, so you can leave your locker as soon as the noise is heard.

Following the same strategy for A-50, it is advisable to keep two-player groups between everyone, as to give all players a chance to claim a locker, and survive all Monsters's attacks.

Be careful for A-200 even if you haven't opened it's door yet.

If both A-50 and A-200 spawn simultaneously, listen closely to both of their own respective despawn indications, before leaving your locker.

Like A-50, A-200 will stay longer the more times that it is encountered, keep this in mind as to not second-guess yourself on if A-200 even spawned, or if it has despawned yet. (However, even though it does stay for longer, it's speed does not increase.)
