FBO was infamous among gamers as both a masterpiece and an absolute garbage fire. Its countless hidden mechanics, obscure events and brutally unfair balancing constantly overturned everything players thought they understood about the game. But for one hardcore player, mastering all of that nonsense was precisely what made FBO the game he loved more than any other. Then he wakes up inside it. Unfortunately, he hasn't reincarnated as the hero, a legendary warrior or even a named supporting character. He's Liberta, a starving orphan so insignificant that he never even appeared in the game's story. For anyone else, that's a terrible starting position. For someone who spent countless hours uncovering FBO's secrets, it's the opportunity of a lifetime. Liberta immediately begins exploiting every obscure mechanic he remembers. Instead of buying expensive equipment, he deliberately purchases mountains of seemingly worthless junk to trigger a hidden event and obtain an indestructible bamboo spear. Rather than hunting powerful enemies, he endlessly massacres the weakest monsters because he knows a secret method for permanently increasing his base stats. To everyone around him, his behavior looks completely insane. To Liberta, it's simply optimal leveling. As he encounters other supposedly insignificant characters like Nell and aspiring songstress Amina, Liberta begins turning a collection of forgotten “mobs” into something the original game was never supposed to contain: an overwhelmingly powerful party. Armed with obsessive game knowledge, hidden quests and every exploit FBO has to offer, a nameless background character begins his speedrun toward becoming the strongest person in the world.
