Where to buy Cyberphobia: Prologue - Expansion Pass 45 at the best price? As of 9 Nov. 2026 this title has one offer, C$249.99 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 C$249.99 today, which puts the pair at C$499.98. 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 45

Cyberphobia: Prologue - Expansion Pass 45 - about the game
⚓ Barnacle & Brine: The Abyssal-Amnesia – Leviathan’s Lure

Submerge the Ego. Scavenge the Wreckage. The dry, rational surface has been swallowed by a crushing, salt-choked depth of memory and rust. The "Abyssal-Amnesia" isn't a drowning; it’s a high-pressure baptism in the ruins of the forgotten. By activating the Leviathan’s Lure, you aren't just a diver—you are the phosphorescent beacon in the sunless trench. This immersion grants immediate Hydrostatic-Agency for all current-riding mobility, ink-cloud decoys, and sonar-ping detection at a reduced Oxygen-Debt.

The Waterlogged Logs (Trench Campaigns)
  • The Coral Catacombs: Descend into the "Calcified Hull-Gullies," a jagged underworld of skeletal shipwrecks and stinging polyps. The "Rust-Mites"—microscopic scavengers that eat through protective plating—track your movements by the electrical hum of your gear.

  • The Pressure-Crush Plague: A localized "Depth-Spike" is increasing the gravitational weight of the water to lethal levels. You must activate the "Ballast-Tanks" to equalize the sector before your physical form is flattened into a thin layer of organic silt.

  • The Cephalopod Cartel: Infiltrate the glowing "Bioluminescent Spires" of the Kraken-Lords. A silent, ink-stained war has erupted between a radical "Bottom-Feeder" insurgency, a fleet of "Harpoon-Sled" raiders, and a massive, many-eyed Deep-Sea Intelligence that dreams the reality of the ocean into existence. Will you cut the tentacles or join the swarm?

⚙️ Salvager’s Apparatus & Nautical Hardware
  • The Beachcomber’s Rig (Utility Expansion): Equipment designed for a life lived under thousands of tons of liquid. Includes Flipper-Jet Boots, Emergency Air-Bladders, and Barnacle-Grip Gloves for scaling slippery, vertical bulkheads.

  • Maritme Armory (Weapons Expansion): High-impact tools for the underwater enforcer. Features the Pneumatic Spear-Gun, the Depth-Charge Mortar, and the Trident-Shock Prod (which delivers a high-voltage stun through conductible saltwater).
