2XKO

2XKO is a 2v2 tag-team fighting game where players select two characters from the League of Legends universe. The game emphasizes strategic team play, allowing players to switch between their Point (primary) and Assist (secondary) characters using a tag system. Players can move their characters using standard directional inputs.

The game includes dashes, jumps, and air dashes to enhance mobility. The control scheme features light, medium, and heavy attacks, with each character having unique normal and special moves that can be executed using specific button combinations. Special moves are performed with a combination of directional inputs and attack buttons. Supers, which are powerful moves that consume meter, can be executed by pressing either light, medium, or heavy, and a special move button.

Initially announced in 2019 as Project L, the game was later rebranded to 2XKO. It is being developed by Riot Games in their Los Angeles, Sydney and San Francisco Bay Area studios, formerly known as Radiant Entertainment, and was released in January 2026 for PlayStation 5 and Xbox Series X/S. The game was made available in early access for PC on October 7, 2025. Music was a key part of the game design that Jesse Zuretti worked on, based on briefs from Mike Pittman and Eugene Kong's briefs about each character; with the key challenge being making a fighting game soundtrack feel exactly like it should.

A closed beta for 2XKO launched on September 9, 2025, featuring ten playable characters. During the beta period, Riot Games released several patches that addressed character balance, improved matchmaking, and fixed bugs. The closed beta received a positive response from players and press, with reviewers noting the depth of the tag-team system and the effectiveness of the parry mechanic. On September 25, 2025, Riot Games announced that the closed beta would transition directly into early access on October 7, 2025, skipping the typical gap between beta and launch phases.

The PC and PlayStation 5 versions of 2XKO both received generally favorable reviews from critics, according to the review aggregation website Metacritic. Fellow review aggregator OpenCritic assessed that the game received strong approval, being recommended by 100% of critics.

It was nominated for "Best Fighting Game" at The Game Awards 2025, and for "Fighting Game of the Year" at the 29th Annual D.I.C.E. Awards, but lost against Fatal Fury: City of the Wolves and Mortal Kombat: Legacy Kollection, respectively.
