a.k.a. The Molten. WARNING: A-0030 is kinda loud, I would reccomend turning down your volume. What it does: A-0030 will spawn at the first room and progress to the latest room at 2.87 RPS, killing anyone unhidden. Once it reaches the current room, it burns the door and despawns. Tables are 100% safe against this entity. To survive, hide.
