From Polygon: “Overwatchs annual Summer Games event has arrived, and it kicked off on Tuesday. The event will run from July 16 through Aug. 5, and offers a host of new skins, emotes, highlight intros, and other collectible cosmetics. In addition, last years cosmetics are all back at a discounted price. Lucioball also returns, offering Rocket League-style soccer action for players in both casual and competitive queues.
One new change is that this event has three weekly challenges. Week 1, which runs from July 16-22, asks players to win nine games. Every three wins, they will unlock a new prize: a Roadhog and Junkrat shark attack spray, a boxing-themed pachimari icon, and finally a snazzy USA-themed Reaper skin.”
