The World Protection Organization
Before you begin a game of Overwatch, you'll need to choose a hero to play. Maybe controlling a cannon-toting, genetically-engineered ape from the moon appeals to you. Or, you might prefer zipping around as a teleporting, time-traveling freedom fighter. Who do you want to be?
In Overwatch, you control one of several heroes in competitive 6-person team shooting matches. Battle over objectives, take down the other team, and achieve victory.
