TRAILER

WHAT IS HAERESIS ?

Haeresis throws you into a relentless, supernatural battle where survival demands both skill and sacrifice.

In this fast-paced FPS, you play as Ignatius, a former commando-turned-priest whose refuge is overrun by demonic forces. Armed with fragile faith and a cursed arsenal, you must purge the horrors invading your sanctuary, face relentless monstrosities, and seal the infernal portals threatening to consume the world.

But every kill feeds the corruption within you. As your gauge rises, so does your power—unlocking devastating abilities at the cost of your humanity. Will you embrace the darkness for strength, or sacrifice your vitality to cleanse your soul?

With its roguelike structure, adaptive environments, and brutal combat, Haeresis delivers an intense and ever-evolving experience, where every run is a battle against both the hordes of Hell and your own descent into damnation.

THE GAME MECHANICS

THE CORRUPTION SYSTEM & DEMONIC PACTS

Each enemy killed fills a corruption gauge, visible on the HUD. At 25%, 50%, and 75%, weapons gain powerful upgrades. But if corruption reaches 100%, the player loses control and transforms into a demon. To survive, they must balance power and restraint. The player can also forge demonic pacts, granting unique abilities at the cost of dangerous curses, radically altering each run.

SKULLS & ITEM PURCHASES

Enemies drop skulls, a cursed currency used to purchase cards and items that provide various benefits: weapon modifications, temporary buffs, or high-risk curses. Every purchase shapes the gameplay, requiring strategic adaptation.

A RELENTLESS BESTIARY

From relentless HellSpawner that chase the player, to guardians punishing immobility, priests buffing surrounding enemies, and Flesh-hunters striking with lethal speed—each encounter is a challenge that demands quick thinking and adaptation.

ADAPTIVE ENVIRONMENTAL MECHANICS

The world reacts to the player's corruption level: doors open or close, cursed blood pools either heal or harm, traps activate or deactivate... The environment becomes a dynamic element of gameplay, offering both new opportunities and constant danger.
