If you still haven't tried out Overwatch, now you have a chance to jump in cheaply. Right in time for the holidays, Blizzard has discounted the PC version of Overwatch by 50%--bringing the price down to $20. And if you're looking to get a bunch of cosmetic items, too, you can grab the Game of the Year Edition for $30--bringing it in line with the PS4 and Xbox One versions.

These are some of the better deals we've seen on the game since its release, especially $20 for the base game. If you're just looking to jump in and don't need a handful of skins and Loot Boxes, then this is the way to go.
