Starts at lobby, and quickly makes its way towards the main room, upon reaching the room it'll aim for the blue locker and check it, right after it'll ram into it, upon hitting the blue locker it'll break and kill anybody inside it. A-450 will the rush back to lobby to rebound , once entering the room again it'll repeat the process, but with the regular gray locker. A-450 will repeat this one more time, but instead with tables, A-450 will despawn 0.5 seconds after it have flung the table.
Upon A-450 despawning, it'll darken a bit before fading *Due note he won't be able to hurt you during this process* A-450 will start it's mechanic once it's spawn sound has hit the 5.05 mark. Upon A-450 ramming a hiding spot it'll break it and fling it at the same time. Every time A-450 leaves the room, it takes it a reasonable amount of time to come back.
