Bethesda’s Dishonored and the upcoming Dishonored 2 are single-player games. But could a future installment in the franchise add some kind of multiplayer, specifically co-op? Don’t bet on it.

In an interview with GameSpot today, Dishonored 2 creative director Harvey Smith said he “would love” to add co-op to Dishonored. However, he shared a story about how the introduction of co-op to a traditionally single-player game ruined the experience and soured him on the idea for his own projects.

He told us that System Shock 2 is one of his favorite games, and he and a friend were very much looking forward to the patch that added co-op. However, when he and his friend finally tried it out, Smith said the results left much to be desired. “It ruined the experience,” he said.

This is because another player can move through the world however they want; Smith cited examples of his friend bunny-hopping down a hall and shooting everything that moves. This isn’t how he plays, and as such, what made System Shock 2 such a great game was now ruined.

“It went from being scary and [making you feel] very immersed in what’s going on…and then you’re watching your friend…boing, boing, boing,” Smith explained about his friend hopping around. “Maybe there is a way to do it, but not for this series, I think.”

Dishonored 2 launches on November 11, 2016 for PlayStation 4, Xbox One, and PC. Earlier this week at E3, Bethesda confirmed that you will be able to play through the entire game without any powers. We also learned about a Dishonored 2 collector’s edition, while Bethesda confirmed that preordering the game gets you a copy of Dishonored Definitive Edition.
