Product listings for Devil May Cry 5 appear to have revealed a feature that Capcom itself hasn't announced yet. The game listings on Steam, the Xbox Store, and the PlayStation Store all list an online multiplayer component. The Xbox and PlayStation listings specify that it's for 2-3 players, while Steam says that it's co-op play.

"With Devil May Cry 5, we are focused on delivering a complete single-player action experience," a Capcom spokesperson told GameSpot." "No multiplayer features have been announced."
