Overwatch's Competitive mode will be back towards the end of June
A competitive mode for Overwatch was featured in the closed beta, but omitted from the open beta because of player feedback. Game director Jeff Kaplan has said that there are plans to implement it into the finished game, but not until “sometime towards the end of June.”
Kaplan said that Competitive mode will be the first big content update for Overwatch. “Competitive mode is the current focus of the Overwatch team, and it's the most important thing for us to add to the game right now,” he said in a live Facebook interview.
