Bandai Namco Entertainment has announced that the online multiplayer service for One-Punch Man: A Hero Nobody Knows will be discontinuing on February 8, 2022. However, 1-online 1v1 matches and offline modes will remain playable.
In this three-on-three action fighting game, players form teams of three characters to face an opposing team. If they choose Saitama, the characters must survive long enough for him to arrive via the "Hero Arrival System." By performing well in battle with only two characters, players can reduce the amount of time it takes for Saitama to arrive.
Furthermore, One-Punch Man: A Hero Nobody Knows was released for PlayStation 4 , Xbox One , and PC in February 2020.
