Blizzard Entertainment has announced that Summer Games is returning to Overwatch again this year. The annual summer event will return August 9 and continue to August 30.

Summer Games first came to Overwatch in 2016 in celebration of the Olympics. The event unlocks content drops of exclusive summer-themed hero skins, as well as Lucioball--a Rocket League-type game mode. Lucioball returns for Summer Games 2018, and promo images seem to suggest the mode's arenas are moving to Busan, South Korea.

Also this summer, Blizzard is teaming up with Twitch Prime to bring players several in-game rewards for Overwatch. To unlock them, link your Blizzard and Twitch Prime accounts. The first set of rewards are available right now. Until September 3, all Twitch Prime members can claim two loot boxes that each contain four random items for Overwatch's newest hero: Wrecking Ball.

Starting in September, Twitch Prime members can also unlock a Golden Loot Box. Another Golden Loot Box will be available for Twitch Prime members in October. None of the boxes contain a fixed set of items, and they don't unlock season event items either.

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