I have no idea why Overwatch is free this weekend. Free weekends are usually the domain of games that are struggling to find an audience. Overwatch is not that game. Obviously.
Maybe Blizzard is just like, bugger it, let's crush every single competitor in the market in one fell swoop.
Either way, a reminder: Overwatch is free this weekend, you should play it. You're probably already playing it. Play it some more.
All hail Overwatch.
Starting from the predictably awkward time of 4am (thanks Australia) you can download Overwatch on the PlayStation 4 or the Xbox One. The game will remain free until 9am this coming Tuesday. Now might be a good time to pull that age-old Monday sickie. All players on the 22-strong Overwatch roster will be available.
Also: if you decide to buy the game once the trial period is up, the game will save your progress. This is also pretty cool.
