Where to buy Cyberphobia: Prologue - Expansion Pass 85 at the best price? As of 9 Nov 2026 this title has one offer, ÂŁ164.99 at Steam. On PC that is the usual case, because only about one title in four gets a keyshop offer and the rest stay with the platform store. There is nothing to compare, but we track this price daily and show how it stands against earlier readings, and a price alert will tell you about any drop. This is an add-on, so you also need the base game to play it. That costs ÂŁ164.99 today, which puts the pair at ÂŁ329.98. On PC you buy a key that you activate in Steam or another client, and this is the widest market we track, with more than a quarter of games carrying a keyshop offer.

About Cyberphobia: Prologue - Expansion Pass 85

Cyberphobia: Prologue - Expansion Pass 85 - about the game
⚗️ Quicksilver & Quartz: The Magmatic Mutation – The Alchemist’s Lead-Lined Ledger

Stoke the Fire. Distill the Truth. The era of the mundane metal is molten; "The Magmatic Mutation" is a glowing, sulfur-scented rebirth. With The Alchemist’s Lead-Lined Ledger, you aren’t just a worker—you are a catalyst in the divine reaction. This clearance grants immediate Forge-Priority for all heat-haze cloaking, mercury-slide dashing, and thermal-shock endurance at a significant Brimstone-Discount.

The Blueprints of the Burning Crucible (Volcanic Expansions)
  • The Basalt Bottleneck: Navigate the "Geothermal Glass-Works," a vertical labyrinth of flowing lava-conduits and pressurized alembics where the city’s central Smelting-AI has developed a volatile, god-like ego. The bubbling in the floorboards isn't gas—it’s the city trying to temper your skeleton into indestructible glass.

  • The Midas Fever: A suffocating haze of "Aerosolized Gold-Isotopes" and "Molten Mist" is drifting through the mines, turning the inhabitants into unmoving, solid-gold statues with frozen, terrified stares. You must reach the Cooling-Tower to quench the air before the "Aureum Fever" crystallizes your blood into heavy, yellow metal.

  • The Obsidian Alembic-Spire: Infiltrate the soaring, soot-stained towers of the Sulfur-Kings. A three-way elemental war has ignited between a radical "Carbon-Pure" soot-cult, a fleet of steam-powered salamander-tanks, and a sentient, ruby-encrusted Centrifuge-Processor housed in a vault of liquid mercury. Will you stabilize the reaction or trigger a volcanic collapse?

⚙️ Transmuter’s Rigging & Heat-Tempered Hardware
  • The Chemist’s Satchel (Utility Expansion): A suite of "Slag-Proof" tools designed for industrial sabotage. Includes the Molten-Glass Grapple, Sulfur-Cloud Smoke-Bombs, and Lead-Weighted Asbestos-Boots for silent navigation across glowing-hot grates.

  • Alchemical Armaments (Weapons Expansion): High-velocity hardware that uses chemical reactions to hit like a landslide. Features the Pressurized Mercury-Spitter, the Obsidian-Glass Khopesh, and the Liquid-Phosphorus Fire-Grenade.
