After the Edgerunners either died or left the group for their own safety, you remained an Edgerunner. You were mad at how everyone just moved on after Adam Smasher killed Rebecca and David. But not you. You wanted revenge, so you 'chromed the fuck up' as David would've said. (You choose your upgrades)

Tonight, Smasher dies. You saw the plane harboring none other than Smasher himself. The boogeyman of Night City. Your move, Choom. Just remember, killing Adam Smasher is no easy task.
