This is tough. It’s not the outcome that any of us had hoped for. I’ve been playing fighting games for over 30 years, made so many amazing friends along the way and have been lucky to experience some unbelievable moments across many legendary titles. I dreamed of one day creating something special for the FGC to help enable even more of those moments. I wanted to give back to the community that had given me so much. 2XKO is the culmination of that dream. This is a dream shared by every member of our team. The amount of love and passion everyone who has ever worked on this game has put into it is unreal. The team delivered a fighting game where you could fight against your friends or choose to take on the world together alongside them. They delivered and elevated League of Legends champions in ways that only a fighting game could. We made a called shot when 2XKO was born as a mixed mode solo/duo game that if two of the top 8 slots of Evo were Duos, then we have achieved our goal of making playing with a friend a competitively viable endeavor in fighting games. The Evo crowd was treated with the first 2XKO top 8 match on finals day being a duo vs duo match sending one team home and deciding who is the strongest duo. This was unbelievably special for the team. Even though we are ending active development at the end of the year, I am glad that folks will be able to play 2XKO beyond that, and that the love poured into it will live on. The team is giving everything they’ve got to deliver a final version of 2XKO to you that everyone can be proud of. We can’t wait for you to play Lux and Samira, so please look forward to them. Thank you to everyone who has worked on 2XKO for creating a really special game, and thank you to all of the players who created moments we will never forget.

I'm looking for a Principal Software Engineer for Rendering on the League MMO This isn't a status-quo role; you'd basically be our go-to person for all things rendering. Building engine tech from the ground up, keeping performance in check at MMO scale, and making tools our artists genuinely enjoy using. You'll be working closely with art, design, and production, so it helps if you like thinking about the player experience as much as the tech itself. Need: 8+ yrs in rendering eng (2+ leading a team), deep UE/Unity experience, multithreaded systems chops, comfort at MMO scale. Nanite/Houdini/UE5 PCG a plus. Our players deserve world-class rendering. Let's build it. Apply: riotgames.com/en/work-with-u…

This weekend was another reminder of how hard building MMOs truly is. They demand grit, resilience, long-term vision, deep player insight, and mastery of complex systems at scale. If that’s exactly what excites you, if you’re a master of your craft and love the League universe, join us in creating something special: riotgames.com/en/work-with-u…

That was my favorite worlds finals series of all time, just amazing! Every single game was a completely fresh draft. Seeing these two great teams adapt and fight all the way to the end. I just loved it. #Worlds2025
