A-120, at a certain distance, makes no more than loud, static-like sound effects. Once within close proximity, an electric amp sound edited to sound like distorted morse code plays, indicating A-120's rapid approach. A-120's more distinctive trait is its ability to summon minions, also called M-120, which spawn during the entity's stationary phase. These minions will aimlessly wander around the room they have spawned in, they will also fire off yellow orbs which are bullets.
