When Ballistic's image accidentally leaked online, many were quick to point out that the Apex Legends character seemed to be holding a smart pistol from Titanfall. This is only half true. His tactical is called Whistler and sees him use modified smart pistol tech to fire a bullet that can track targets, potentially overheating their weapon if they continue to use it for too long. It's a powerful tactical, one that shifted him from a weapons-based support legend to a full-blown assault character in development, but it was once something else entirely—a turret.
