You either have to have a PS4, Xbox One or a PC. Which ever one you have, go to GameStop and buy the Overwatch game. If you have a PC, you have to buy from another store like Walmart, Target or Best Buy. You also have to have Plus for the PlayStation or an Xbox live gold subscription to play considering its an online game. It’s easier to pay $50 for a whole year. Then, take it home and install the game and there you go, you can play.
