This isn't one of those severely limited free trials, either. All 27 heroes and 18 maps are available to play, as are most of the modes. You can level up, collect Loot Boxes, and unlock things like outfits, emotes, and sprays for the characters. And if you decide to buy the game, you'll get to keep anything you earned during the free weekend--just make sure you're using the same Blizzard, Sony, or Xbox Live account.

While Xbox One owners need an Xbox Live Gold subscription to take part in the free weekend, PS4 owners don't need a PS Plus account to participate. Windows PC owners will need a Battle.net account to download and play the free trial.

The free-play window runs between May 25 at 11 AM PT / 2 PM ET and May 28 at 11:59 PM PT / May 29 at 2:59 PM ET.
