Overwatch is in the midst of celebrating its one year anniversary with a special in-game event, but the celebration is coming to an end on Monday, June 12th. To make sure that Overwatch‘s one year anniversary celebration ends with a bang, Blizzard is hosting a rare double XP weekend for the game, which will begin on Thursday, June 8th and conclude on Monday alongside the event.

Blizzard announced Overwatch‘s double XP weekend on Twitter, confirming that players across all platforms will have a chance to boost their levels this weekend. And since this weekend will be the last one to earn One Year Anniversary event items from loot boxes, the double XP weekend is coming at just the right time.

Of course, if players still fail to unlock some of the new skins they want in the final days of the event, they can always bite the bullet and use real world cash to purchase more loot boxes. However, since what players get from loot boxes is random, there is no way to guarantee that they will unlock everything they want from the event.

In the meantime, it will be interesting to see if the end of the game’s One Year Anniversary event and the double XP weekend will lead into some exciting news at E3 next week. Rumors have been swirling that Overwatch will have a presence at the show, with some fans theorizing that the game’s next character will be officially announced at some point during the event.

If a new Overwatch character is announced at E3, it seems likely that it would be one of two characters that are assumed to be in the pipeline. One is supposedly an chimpanzee support character, and the other is Doomfist, who has  been rumored for the game for the last few months.

E3 presence or no, Overwatch fans still have a few days to celebrate the game’s anniversary. And they can do so by grinding for loot boxes to unlock some of the event-exclusive items, which should be made much easier thanks to the double XP weekend.

Overwatch is available now for PC, PS4, and Xbox One.
