2XKO Control Diagram

Control Diagram

2XKO uses standard directional inputs for movement: up (↑), down (↓), back (←), and forward (→). For offensive inputs, the game uses light (L), medium (M), and heavy (H) attacks. Some of these moves can be modified with directional inputs to perform specialized attacks such as cross-ups or anti-air. Each champion has a range of special moves that can be performed with the S1 or S2 buttons. Inputting down (↓) down (↓) + S1 OR S2 spends 1 bar of meter and activates one of two supers, while inputting down (↓) down (↓) + S1 AND S2 spends 2 bars of meter and activates the ultimate, a stronger and more cinematic super.

For defensive options, inputting back (←) or down-back (↙) buttons performs a block, reducing damage from incoming attacks. Inputting forward (→) + L and M performs a pushblock, a block that pushes enemy champions across the screen. Inputting back (←) + L and M performs retreating guard, which cancels a back dash while blocking. Inputting L + H performs parry at the cost of 1 bar of meter, successfully parrying an attack stuns the enemy champion and refunds the meter cost. Inputting down (↓) while parrying modifies it into a low parry.

Tag System[]

2XKO is an assist-based fighter where players pick two champions: the Point and the Assist. The Point is the player's primary champion and performs most of the on-screen actions, while the Assist is a secondary champion that aids their Point in combat with Tag Systems. Champions can swap between being the Point and the Assist with a handshake tag. When played with a duo, one player controls the Point while the other controls the Assist.

Points and Assists have separate health bars. When a Point's health is depleted, the Assist is automatically swapped in as the Point and continues the round. The round ends when both champions are knocked out. The knocked out ally can still impact the match with a powerful, once per round, off-screen move called the Last Stand.

Assists aid their Points with tag systems, actions unique to Assists when summoned. All Tag Systems revolve around the Team (T) button. There are three types of tag systems: Assist Actions, Handshake Tag, and Dynamic Save. Assist Actions are special abilities unique to each champion, every champion has 2 Assist Actions they can perform from off-screen. Assist Actions are performed by inputting forward (→) + T or back (←) + T. Holding T while performing an Assist Action turns it into a Charge Assist. Inputting the T button by itself performs a Handshake Tag, which allows the Point and Assist champions to swap roles as long as they are both on-screen. Handshake Tags can also be comboed with Assist Actions. Inputting S1 or S2 + T performs Dynamic Save, the combo breaker mechanic of the game. It summons the Assist in an attempt to save the Point and can interrupt any combos being performed on them. Dynamic Save can still be used even if the Assist is knocked out.

Fuse System[]

Fuses are powerful synergy options selected in champion select that change up your duo's playstyle. Known Fuses include: Fury, gain bonus damage and a dash cancel while below 40% health; Freestyle, enables 2 Handshake Tags in 1 sequence; Double Down, combos both champion's supers; and 2x Assist, which allows you to perform 2 back-to-back assist actions.

Juggle limit[]

When a character is being juggled (comboed in the air) in this game, there's a counter of how many consecutive hits occurred in the air, below the combo meter. This looks near identical to Rising Thunder's juggle counter, except without a number stating the maximum juggle. In Rising Thunder, when this counter was filled up, the player being juggled became invincible briefly and fell to the ground. Something similar was seen in the gameplay where this meter was seen, where Katarina fell towards the ground after being shot in the air by Jinx, but this could be a completely different mechanic in play.


2XKO will use server-based rollback netcode.[2]


2XKO features stages from the different regions of Runeterra. Currently several stages have been revealed: Bridge of Progress, Spirit Hills, The Brazen Hydra, and Scuttler's Strand.


Not all champions from League of Legends icon League of Legends will be in 2XKO at launch. Champions have abilities inspired by their kits in League of Legends as well unique abilities made without the restrictions of the MOBA. According to Alex 'Blinkity' Jaffe, 2XKO's Lead Champion Designer, they view the character in League of Legends as an "abstraction" and that in 2XKO they are able to make the "real, dense, rich... multifaceted thing that the League kit has distilled down."[3] The champions revealed so far are:

  • This game is developed by the developers from Radiant Entertainment. Radiant was a game developer that was acquired by Riot Games Inc. in March 2016.
    • This game was heavily inspired by Radiant's cancelled game, Rising Thunder.
  • A mod for Super Smash Bros. featuring League of Legends icon League of Legends champions was made and played during the pre-2019 Thunderdome events.
  • The game had a cameo in the GIANTS music video.
  • Katarina Katarina was the original proxy champion used to play test mechanics in 2XKO, but when the game was rebooted to become a tag-team fighter, her abilities became outdated and required a significant revamp and thus was no longer part of the launch roster in 2XKO.[6]

  • From August 4th to 5th, 2023, the game had a playable demo at EVO 2023.[8]
