The biggest 2XKO update yet has arrived, bringing two iconic League of Legends champions—Senna and Thresh—into the fighting game arena. Patch 1.2.3 introduces a wealth of new content, including a PvE mode called The Climb, Pool Party skins, and a fresh take on tag combat. Riot Games' design team has shared an in-depth look at how they translated these beloved characters from Summoner's Rift to the 2XKO roster, highlighting the technical innovations and gameplay philosophies behind the dual champion launch.
Senna's Duality: Light and Darkness in Perfect Balance
Senna's transition to 2XKO presented a unique challenge: how to capture her League identity as both a light-wielding marksman and a master of the Black Mist. Early designs focused heavily on beam attacks and relic cannon zoning, but the team wanted to give equal weight to her shadowy side. The solution was a transformative mechanic that lets Senna switch between two distinct forms: Base Form and Wraith Form.
Base Form Senna relies on her relic cannon to fire massive beams of light, perfect for poking down opponents from a distance. In contrast, Wraith Form—inspired by her League E ability (Curse of the Black Mist)—transforms her into a speedy, shadowy wraith with enhanced mobility and a unique triangle jump, a tag fighter mechanic previously missing from the roster. The team iterated extensively to ensure neither form overshadowed the other, ultimately making the switch fluid and thematic.
Senna also introduces a groundbreaking support mechanic: her Super Assist can heal teammates if it connects, drawing directly from her League Q ability (Piercing Darkness). Originally, this granted super armor to allies, but that proved too powerful, so the team settled on a heal. With two complete kits—each with unique visuals, sounds, and effects—bringing Senna to life took twice the effort of a standard champion.
Thresh: The Chain Warden's Tools for Torment
Thresh's design revolves around a single, crystal-clear theme: he's a villain. The team was eager to bring one of League's few straight-up antagonists to 2XKO, and his nefarious energy is a fresh addition to the roster. His kit is built around two iconic set pieces: the hook (Death Sentence) and the lantern.
The hook required massive technical effort to ensure consistency and readability across all attacks. Animators meticulously tweaked keyframes for each chain-and-hook move, and the advanced rigging setups had to work seamlessly with every Thresh skin. The result is a character who can reposition enemies on screen, forming the core of his combo theory.
Lantern Tag: A revolutionary mechanic that lets Thresh's ally join his combos by 'clicking the lantern,' creating new tag opportunities and deepening team synergy.
The Wretch (Henry): A new summon move (down S2) that controls space on the ground and in the air, leaning into Thresh's identity as a sadistic tormenter with command over the undead.
Advanced Rigging: Technical artists created unique setups for Thresh's chain animations, ensuring every hook and swing feels fluid and impactful.
Early iterations of Thresh had Assist attacks spawning from his lantern location, but this led to gameplay inconsistencies and made him feel disconnected from his teammate. The shift to Lantern Tag brought his kit to life, perfectly capturing the 'click the lantern' fantasy from League.
