A-244 is a fan-made Interminable Rooms entity that can check all hiding spots. He rebounds 2-6 times (Ambush from Doors) and is really fast. RPM limit: 100.2. He stays in the room for 5 seconds. He is impossible to hide from. The only way to survive him is to go to a room with no hiding spots (He's casually blind) and go to the door. Hint from @Sonic7645
