About the Game

ABOUT THE GAME Zaetherfall is a visual novel / shmup focused on a war of factions, propaganda, and decisions made at the edge. Three rival aces—URA, EUPRA, and the Sacred Eastern Dominion—are forced to cooperate as Zael Aether advances as an absolutist theocracy that never negotiates: it purifies. Between missions, the campaign unfolds through visual novel interludes: political tension, cultural clashes, fragile alliances, and the true cost of holding together a coalition that should never have existed. Every faction carries its own internal dramas. In combat, those same fractures surface as real-time communications: orders, friction, pressure… and silences that say more than any speech. In gameplay, Zaetherfall blends arcade pace with clear tools: Power-ups, projectiles, and missiles to control the field. Fire and Plasma weapons to adapt to every encounter. Two shields with short windows and real cooldowns: Plasma Shield (anti-projectile) Fire Shield (anti-missile) Every level culminates in a duel against a Zael Aether Commander: multi-phase bosses with patterns that shift, tighten, and escalate until they break you… or make you stronger. KEY FEATURES VISUAL NOVEL + SHMUP: a story driven by factions, ideology, and political conflict—built around intense action between scenes. THREE PROTAGONISTS, ONE WAR: three perspectives with clashing identities and cultures inside the same cockpit. COMBAT WITH REAL TOOLS: power-ups, projectiles, and missiles to shape the flow of battle. DUAL TACTICAL DEFENSE: Plasma Shield (anti-projectile) / Fire Shield (anti-missile), both with short duration and real cooldowns. DUELS AGAINST COMMANDERS: multi-phase bosses and phase transitions that reshape every encounter. REAL-TIME REACTIVE COMMS: orders, taunts, and last words that track waves, breaks, and boss transitions. THE PILOTS Zack Vásquez — “The Spear of the Americas” Heroic, impulsive, and head-on. His greatest strength is pushing forward; his greatest risk is not knowing when to stop. Ekaterina Väisänen — “The Mind of Europe” A disciplined tactical leader. She believes in unity and teamwork to carry out the mission at all costs. Wei Zhang — “The Silence of the East” Precise, steady, restrained. He fights an inner war—one that demands he believe blindly in his nation. THE DOCTRINE OF ZAEL AETHER They do not speak: they purify. Empire as religion—blood, steel, and void. They call it the Silent Divinity. We call it extinction. Stand with your own. Defy the divine. Burn their heaven.
