Bandai Namco released a new trailer for One Punch Man: A Hero Nobody Knows during Gamescom 2019 which answered the first question that popped up in everyone's mind - how will they balance Saitama? Well, they didn't take his power.
As soon as a One Punch Man game was announced, everyone started asking the obvious question - how will the developers balance out Saitama, the hero that is so powerful that he defeats everything and everyone in a single punch or a slap, even when holding back?
The easy and lazy way out would be to absolutely ignore his power for the sake of balance and require Saitama to land a pile of punches and kicks on the Mosquito Girl instead of splattering her all over a building in a single slap.
Spike Chunsoft wouldn't be satisfied with something like that, as they decided to get creative. Saitama will indeed beat the opponent in a single hit but the catch is that he will not be there from the start of the fight.
According to the trailer above, there is a mechanic called Hero Arrival System, which is a 120-second timer before Saitama arrives on the scene to beat up the baddies. Therefore, weaker heroes like Mumen Rider will actually stand a chance against the likes of Deep Sea King, provided they manage to survive that long.
The timer itself is not inelastic. In other words, you can make it run out faster by fighting better. This includes landing perfect blocks, fighting back and stringing combos. Once the 120 relative seconds are up, the fight is basically over as the Deep Sea King is shown attempting to damage Saitama to no avail. Needless to say, all it took was one hit from the hero to end the fight.
Bandai Namco didn't miss out on the opportunity to tease some of the heroes that will be playable in the game, such as Genos, Atomic Samurai, Hellish Blizzard, Silverfang and some sassy lost child.
As for the villains, the trailer showed Deep Sea King, Mosquito Girl, Vaccine Man, Carnage Kabuto and Speed o' Sound Sonic. Boros is only seen on the promotional art.
