A-60 is the 3rd runner-type entity within Section A, and the first of the two entities from the original Rooms, the second one being A-200. A-60 moves significantly quicker than its predecessor, A-35, and decently slower than its successor, A-100. Whenever it spawns, it'll make a slight static noise to signify that it has spawned, though from afar this may be difficult to hear.
Similar to other runner-type entities in the game, A-60 will spawn inside of the lobby and will immediately depart, rapidly traversing the various rooms the player has already passed and making its way to the latest unopened room. It moves about six times faster than A-10. Upon reaching its destination, instead of simply despawning like the aforementioned entity or rebounding like A-35, A-60 will stop in its tracks abruptly in front of the last unopened door, remaining idle for about four seconds before eventually despawning. This mechanic is to catch players who expect the entity to head back or despawn off-guard.
A-60 acts similar to his original Rooms counterpart, as both start from the lobby and quickly head to the latest room at a considerably high velocity. Notable differences between the two are in its mechanic. A-60 in Rooms will accumulate more speed the more rooms the player progresses through in order to catch up to them. It also remains idle in the room it is currently in if all players are currently hidden inside of lockers, instead of continuing in its track like IR's A-60.
This is also one of, if not the most iconic entity of any Rooms Fangame, as it makes an appearance in most of them and is commonly associated with Rooms.
