EVO, the yearâs biggest fighting games event, went down over the weekend, and in terms of news perhaps the biggest announcement was that not one but two games will be getting Rollback Netcode improvements over the next 12 months. Donât know what that means, or why itâs important? I got you!
So in online multiplayer games, a big part of allowing everyone to play together is the way the game registers everyoneâs actions at the same time. When a person in Canada is playing someone in Germany, theyâll both be pressing buttons in their own homes, and the game needs to pick up those inputs, apply them to the game and have them play out in a way that makes the whole thing look as seamless as though they were playing with (or against) each other in the same room.
Different games (and different genres) handle this differently, depending on how important speed and accuracy is to the playerâs experience, but one type of input recognition thatâs especially important to anyone playing a fighting gameâwhere every frame and millisecond can mean the difference between victory and defeatâis called Rollback Netcode.
Rollback Netcode doesnât rely on waiting for everyoneâs input before registering actions; instead it lets both players press their buttons and see the action play out instantly without lag or delay, as though they were playing offline. In the downtime between that and the opponentâs action arriving, the game basically guesses what was going to happen next. If it guessed right the game continues with nobody noticing, and if it was wrong, it checks down to play out the action that the other player actually made, which sometimes involves a little âteleportingâ.
The very helpful video below, by Code Mystics, explains how Rollback Netcode works, and how in fighting games its speed and accuracy make it so superior to the more traditional Input Delay:
OK! So now that weâre all up to speed on Rollback Netcode, you can understand why such a seemingly minor announcement is actually a huge deal for fighting game fans, and why these two announcements made at EVO went down so well with fans.
First up, producer Tomoko Hiroki took to the stage to announce that the upcoming versions of Dragon Ball FighterZ on PS5 and Xbox Series X|S will be getting Rollback Netcode, as will the PC version. On the latter, players will get the option whether to use Rollback Netcode (which will carry a slightly steeper system requirement) or stick with Input Delay.
It doesnât look like the upgrade will be coming to the PS4, Xbox One or Switch versions of the game, though the last-gen PlayStation and Xbox versions will have upgrade paths made available for anyone who upgrades to newer systems.

As for when this is actually coming, it doesnât sound like it will be soon, with the announcement saying, âIt will take some time until the system is implemented, but we sincerely hope you will enjoy it as soon as possible. More information will be released at a later date. Please wait for further details.â
The 2019 reboot of Samurai Shodown got the same announcement, with SNK teaming up with Code Mysticsâcreators of the video aboveâto implement the upgrade. Itâll be coming to the PC, PS4, Xbox One and Xbox Series X|S versions of the game (again leaving the Switch behind), and is âplannedâ for Spring 2023.
