Riot Games' ambitious fighting‑game project, 2XKO, faced a stark reality check when its chief product officer, Marc Merrill, explained that the title would have required a truly massive monthly active user (MAU) count—"in the high hundreds of thousands, if not millions"—to become financially viable. This insight emerged during a candid appearance on The Lemonade Stand podcast, an interview that was later highlighted by IGN.
Merrill emphasized that, although the game managed to strike a chord with a dedicated niche of players, the broader player pool simply wasn't large enough to underpin the live‑service framework that Riot had envisioned. The development of 2XKO officially halted in August, a decision driven by the fact that the game's operating costs far outstripped the revenue it generated. Even after rolling out substantial updates intended to boost engagement, the metrics remained disappointingly flat.
Despite the cessation of active development, the title remains accessible: it can still be downloaded for free on PC, PlayStation 5, and Xbox Series X|S, and Riot has committed to keeping the servers online at least through 2026, allowing existing fans to continue playing. Merrill also pointed to external market forces that compounded 2XKO's challenges, most notably the release of Capcom's Street Fighter 6. He reflected that Riot had a limited window to make a meaningful impact on the fighting‑game community, but the arrival of Street Fighter 6—arriving roughly eight years after Riot began work on 2XKO—diluted the attention and enthusiasm that might have otherwise coalesced around Riot's offering.
"We had a fantastic development team, incredibly talented, that built a beautiful game," Merrill said. "We communicated our vision to the community and decided to push forward, hoping the audience would grow." He went on to suggest that timing was a crucial factor: "If we had launched years before Street Fighter, ideally when we should have, we likely would have made a significant impact." This hindsight underscores how competitive the fighting‑game space is, where major releases can dominate player interest and make it difficult for newcomers to gain traction. The origins of 2XKO trace back to Riot's 2016 acquisition of Radiant Entertainment, a studio known for the free‑to‑play fighting prototype Rising Thunder, which entered alpha in 2015. Rising Thunder served as a primary source of inspiration for 2XKO's design philosophy.
After the acquisition, Riot removed Rising Thunder from commercial storefronts and eventually cancelled its development, later releasing the code as open source in 2017. Merrill explained that Riot sought to blend Rising Thunder's streamlined controls and compelling 1v1 combat concept with the rich League of Legends intellectual property, specifically integrating characters like the Cannon brothers, and to overlay this hybrid with Riot's signature competitive ecosystem. This vision gave birth to 2XKO, aiming to deliver a fresh, accessible fighting experience anchored in Riot's broader gaming universe.
However, the project encountered internal turbulence as well. Shifts in leadership led to a misalignment of strategic priorities, creating what Merrill described as "managerial fracturing." Teams received mixed messages about the game's direction, which hampered cohesive execution.
In reflecting on these challenges, Merrill took responsibility, noting, "We've got nobody to blame but ourselves," acknowledging that both external market pressures and internal organizational discord contributed to the outcome. The broader lesson from 2XKO's journey highlights the difficulties of launching a live‑service fighting game in a saturated market. Even with a strong development team, a beloved IP, and a clear design vision, success hinges on achieving a critical mass of active users to sustain ongoing operational costs. Riot's commitment to keep the servers running through 2026 demonstrates a respect for the community that did form, offering them continued access while the company likely assesses future strategies for entering the fighting‑game genre.
Looking ahead, Riot may draw on the experience of 2XKO when considering future projects. The company has shown a willingness to experiment beyond its flagship MOBA, and the insights gained—from user acquisition challenges to the importance of timing relative to competitor releases—could inform more refined approaches.
Whether through revisiting the core concepts of 2XKO, leveraging other IPs, or exploring entirely new gameplay frameworks, Riot's foray into fighting games remains a valuable case study in balancing creative ambition with the hard economics of live‑service models. In summary, 2XKO's story is one of high aspirations tempered by practical realities: a need for a massive, engaged player base, the impact of competing titles like Street Fighter 6, and internal strategic missteps all converged to limit the game's longevity. Yet the game's continued availability and the transparency of its creators provide a foundation for future innovation in the genre.
