Hellfire Fighters is DarkGaming's newest series. It is an umbrella game featuring many characters, such as Mario, Sonic, Spiderman, or Megaman.
In the first game, the story is that XANA's army interrupts the Tournament of the Stars, and now Mario and the gang are racing against time to stop XANA's grand takeover of the Multiverse.
In the sequel, we learn that it was Bill who revived XANA so he could destroy the Multiverse. But now, it seems Bill has to do the fighting himself. He assembles in army, including Bowser, Eggman, and his prime general Herobrine, to destroy the Multiverse.
