Arc System Works and Atlus have released a new beta for the PC version of fighting game Persona 4 Arena Ultimax, finally adding rollback netcode to the game’s multiplayer. Check out the trailer for the new feature below. Rollback netcode is essentially a method of interpreting inputs between players in a multiplayer match that allows for predictive responses and the ability to rollback—hence the name—any action that might conflict with what players actually did. Rollback netcode is typically seen as a superior method of playing multiplayer fighting games over large distances online, since the more commonly-used delay-based netcodes ends up feeling quite bad to play owing to its nature of slowing the game down and causing input-delays.
