Riot Games and Mastercard has announced that the two will continue to work together in the competitive League of Legends scene going forward. As noted in a tweet by the latter, Mastercard will continue as the official sponsor of the World Championship, the Mid-Season Invitational, and the All-Star tournament, and will now also be a sponsor of each events' opening ceremony.
"We're happy to announce an extension of our global partnership with @lolesports
Alongside @Riotgames, we're looking forward to continuing to level up the esports experience, bringing fans closer to the esport they love"
As is the case with many of the sponsors tied to competitive League of Legends, Mastercard will also be featured in-game via logo placements, as well as its logo popping up on official merchandise as well.
Looking at Worlds 2022, the tournament is currently continuing with the Group Stage, with the intent for the premier event to wrap up in early November.
