The Felsan Repository key art

The Felsan Repository is a first-person survival experience set in a fractured reality where worlds overlap, collapse, and reassemble in real time. Blending intense horde-based combat, strategic companion defense systems, and quiet moments of respite, the game challenges players not just to survive—but to endure.

Reality is unstable. The longer you fight, the more it changes.

Game Overview

At its heart, The Felsan Repository is about pressure and relief.

Players face escalating waves of crystalline, corrupted entities in fast, unforgiving FPS combat inspired by classic survival modes. Ammunition is limited. Positioning matters. Every mistake compounds.

Between the chaos, players find rare pockets of calm—Ephemeral Lounges—spaces that exist outside the flow of combat where time slows, the noise fades, and survival becomes reflection.

You never leave the world. The world simply gives you a moment to breathe.

Key Features

Survival Mode

Survival Mode

Endless pressure. Finite choices.

Face relentless waves of corrupted entities in a brutal survival experience inspired by classic horde modes. Every round escalates in intensity, forcing players to balance positioning, firepower, upgrades, and risk. Survival isn't about perfection -- it's about lasting one more cycle.

Death is inevitable. How long you resist is the challenge.

The Ephemeral Lounge

The Ephemeral Lounge

A place that exists between fights... and between worlds.

Step into a transient sanctuary outside the chaos. The Ephemeral Lounge serves as a social, narrative, and progression hub where time slows, stories surface, and reality feels thinner. Interact with characters, unlock lore, modify builds, or simply exist for a moment between collapses.

Not all battles are fought with weapons.

Waifu Defense Platforms

Waifu Defense Platforms

Sentinels, not turrets.

Deploy specialized NPC companions on elevated platforms to control the battlefield. Each guardian provides unique combat support -- precision fire, area denial, buffs, or reality-bending effects -- functioning as living defensive systems rather than static towers.

Placement, synergy, and timing matter. These allies don't just protect you -- they shape the fight.

The Story So Far...

Everyone knows Code—the one who can merge collapsing branches and restore reality. You are not him. You are a soldier sent ahead into unstable worlds to make them safe enough for his arrival. Each branch is fractured, corrupted, and failing, and your job is to hold the line, stabilize what you can, and survive long enough for the merge to happen. Most soldiers don’t. If you succeed, Code will arrive, history will move on, and your role will already be over.
