Lore & Background
In the chaotic sprawl of New Eridu, Billy Kid is known for his flamboyant style and unshakeable loyalty to the Cunning Hares. However, no official side story has explored a specific Hollow event tied to his past trauma or revealed a nickname like 'Shell'. Billy's backstory remains largely mysterious, with only hints of a troubled history. The claim that a particular Hollow reflects his internal state or that he must confront echoes of his past is unsupported by current game content.
In Their Own Story
The neon lights of New Eridu flickered and died as the air grew heavy with static. Inside the Hollow, the world wasn't made of stone or metal, but of shattered glass and forgotten laughter. Billy stood at the edge of a precipice that led not down, but into a memory he had locked away years ago. The Ethereals here didn't roar; they whispered his name in voices long silenced. He gripped his weapon, knuckles white, feeling the familiar weight of the shell closing around him. "Just another job," he muttered to the empty air, though his voice trembled. But as the first shadow lunged from the mist, he realized this wasn't a hunt for loot or glory. It was an exorcism.
Reader's Guide
The Shell side story begins with a seemingly routine investigation that quickly spirals into a personal confrontation for Billy Kid. Players must navigate through a Hollow that reacts dynamically to Billy's emotional state, requiring strategic combat and careful exploration. Mission objectives shift from standard elimination tasks to narrative-driven moments where players uncover fragments of Billy's past. These segments often involve solving environmental puzzles or making choices that reflect Billy's internal conflict between his current life with the Cunning Hares and his traumatic history. The emotional climax occurs when Billy is forced to face a manifestation of his deepest regret. This sequence demands high-level combat skills but also rewards players with a profound character revelation, solidifying the bond between the protagonist and the Cunning Hares.
