A Twitter user called Lifeless Galaxy recently tweeted at Mass Effect: Andromeda's lead designer Ian S. Frazier about a gun that appears in a cutscene for the game, but isn't playable, the X5 Ghost, and Frazier responded, indicating it might be playable in the future.
"That is the X5 Ghost," he said. "It was an early idea that become a prop, but doesn't exist as a functional gun in the game. That said, several folks seem interested in it, so we're investigating the possibility of turning the prop into a usable gun for a future patch."
Did you notice the X5 Ghost going missing?
