Riot Games' highly anticipated 2XKO (formerly Project L) is set to revolutionize the tag-team fighting game genre. This article explores its innovative tag-team mechanics and the recently available playable demo.
Reimagining Tag-Team Combat

2XKO, showcased at EVO 2024, introduces "Duo Play," a unique twist on the 2v2 formula. Instead of one player controlling both characters, two players team up, each controlling a champion. This results in four-player matches, with teams of two. Each team features a "Point" character (the primary fighter) and an "Assist" character. Even 2v1 matchups are possible.
The tag system incorporates three key mechanics:
- Assist Actions: The Point character can summon the Assist for special moves.
- Handshake Tag: The Point and Assist instantly swap roles.
- Dynamic Save: The Assist can interrupt enemy combos.
Unlike some tag fighters where a single knockout ends the match, 2XKO requires both players on a team to be defeated. However, defeated champions remain active as Assists.
Strategic Synergy: The Fuse System
Beyond character selection, 2XKO introduces "Fuses"—team-based synergy options that modify gameplay. The demo featured five Fuses:
- PULSE: Rapid attacks trigger devastating combos.
- FURY: Below 40% health, increased damage and special dash cancel.
- FREESTYLE: Allows two Handshake Tags in quick succession.
- DOUBLE DOWN: Combine ultimate moves with your partner.
- 2X ASSIST: Grants the Assist character multiple assist actions.
Game designer Daniel Maniago highlighted the Fuse System's role in enhancing player expression and enabling powerful coordinated attacks.
Champion Roster and Alpha Lab Playtest

The playable demo featured six champions: Braum, Ahri, Darius, Ekko, Yasuo, and Illaoi, each with movesets reflecting their League of Legends counterparts. While Jinx and Katarina were previously shown, they are not included in the Alpha Lab Playtest but are confirmed for future release.
2XKO, a free-to-play title, will launch on PC, Xbox Series X|S, and PlayStation 5 in 2025. Registration for the Alpha Lab Playtest (August 8-19) is currently open. Further details can be found in the linked article.
