About Breach Protocol

BREACH PROTOCOL

The facility has gone dark. The corporation wants answers. You want out alive.

Breach Protocol is a biopunk action roguelite that throws you into the heart of a research installation consumed by an alien biomass that has rewritten the rules of biology, architecture, and loyalty. Every run is a descent into procedurally generated combat arenas where positioning, resource management, and split-second decision-making determine whether you extract with your life — or become part of the infestation.

FAST, BRUTAL COMBAT Fight through waves of increasingly dangerous enemies using a fluid isometric combat system built for aggressive play. No hiding. No waiting. The biomass rewards pressure and punishes hesitation. Master your loadout, exploit enemy weaknesses, and push the arena to its limits before it pushes back.

BUILD YOUR RUN Every arena cleared is a chance to evolve. Choose upgrades, unlock new abilities, and construct synergies that compound with each room you conquer. No two runs play alike — and no two players will build alike either.

A HUB WORTH RETURNING TO Between runs, retreat to the last safe pocket of the facility where six survivors have made an uneasy home. Each carries their own history with the corporation, the biomass, and you. Deepen those relationships to unlock permanent upgrades, new narrative paths, and content that changes what you find in the depths.

THE FACILITY REMEMBERS The deeper you push, the more the facility adapts. Enemy compositions evolve. New threats emerge from the biomass. The architecture itself becomes hostile. Death is not the end — it is data. Every run teaches you something the next one will demand you apply.

FEATURES

  • Isometric action roguelite combat with a deep upgrade and synergy system

  • Procedurally generated arena layouts with escalating threat tiers

  • Six unique hub characters with branching relationship systems and unlockable content

  • Biopunk aesthetic blending hard sci-fi architecture with organic alien infestation

  • Adult content reflecting the brutal, intimate, and morally complex world of the facility

  • Persistent meta-progression that carries the weight of every failed run forward

The corporation sent you in to find out what happened. Now you know. The question is whether you can survive long enough for it to matter.

BREACH IN. FIGHT THROUGH. GET OUT.
