The Overwatch team announced via Twitter that Overwatch would be free-to-play on PC, Playstation 4 and Xbox One for a week, from November 20-26.
The free week comes shortly after Overwatch's newest hero, Ashe, was introduced into the game and is probably aimed at getting new players in to try the hero out.
Overwatch has offered free weekends before, but this is the first time the game is offering an entire week of free-to-play.
Some veteran players like the free weekends because it introduces a lot of new players to the game, who might not be as experienced, which means easy wins.
Console players could use the free week to try out Overwatch on PC, and decide if they want to make the switch.
Blizzard usually offers a sale on Overwatch at the end of the games free week/weekends, giving new players or those who might be looking to switch platforms a little more incentive.
Of course, the free week is also an opportunity for smurfs, veteran players who make new accounts to make other players think they're new to the game, to get their latest accounts up and running.
