Evo 2024 has wrapped up, and while thousands of attendees all turned up to play and spectate their favourite fighting game, lines were long to try out the latest build of one not-yet revealed. 2XKO, Riot Games’ upcoming fighter turned up at the show in a big way, and with it came new information.

Who better to talk about this than Tony Cannon. Creator for GGPO rollback netcode back in 2009, Tony has been somewhat of a striking figure in the pursuit of better online play in fighting games.
