Insufficient adoption, low retention: Riot Games to end active development of 2XKO in December 2026. The League of Legends IP failed to convince fighting game players.

Analysis

The result comes as no surprise to genre observers. The fighting game market is particularly demanding: a fragmented community split between Street Fighter, Tekken, Mortal Kombat, and indie titles, coupled with a steep learning curve that even LoL's massively popular IP failed to smooth out.

An IP does not make a fighting game. Retention in this genre relies on combat system depth, balance, and online competitiveness—not the notoriety of its characters. 2XKO did not seem to win over the hardcore players who form the backbone of any enduring fighting game.

This is not the first time Riot has attempted to expand its catalog. The expansion strategy remains intact, but 2XKO joins the list of projects that failed to find their audience despite a globally recognized launch.

Rating: 4/10Key takeaway: a strong IP is not enough—the fighting game genre demands mechanical depth that 2XKO failed to establish. For whom: LoL fans curious about the genre are left without a destination—and will have to wait for Riot to try something else.
