Speed: Very Fast (8.4 RPS) Mechanic: G-437 will spawn in the main room. It disguises as a human upon spawning. It will start walking around the room. In 10 seconds, it will walk to the middle of the current room and turn into it's actual form. In 5 seconds, it will rush to G-000 at very fast speeds, killing anyone not hiding. Upon reaching G-000, G-437 will despawn.
