Overwatch wasn’t what you’d call a “surprise” hit — everyone knew it was going to wipe the floor with its immediate competition. But unlike a lot of games, it still costs money. If you’ve been meaning to give it a shot but don’t feel like shelling out the $40, this weekend the game is free to play on all platforms (PC, PS4, Xbone) with no restrictions. I guess it’s a Valentine’s Day promotion. Why not, right?

Download Battle.net and register to get started; you can pre-download the game starting tomorrow, with free play beginning midday Friday.
