In a rain-soaked city rotting under corruption, siblings Gonte and Jane wage a brutal, uncompromising war against the criminal networks that destroyed their family. Hunted by rival factions and marked by a bounty, the two operate with cold precision as they carve through enforcers, assassins, and mercenaries drawn to their trail of violence. As the night escalates into a citywide hunt, fragments of a deeper conspiracy surface, one tied to power systems, shadow organizations, and forces far larger than the enemies they face. Catalyst’s Vow captures a single, relentless chapter of their crusade, offering a glimpse into a much broader conflict already in motion.
