Where to buy Cyberphobia: Prologue - Expansion Pass 9 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.

ā˜£ļø Bio-Hazard: The Carrion Protocol – Apex Survivor Bundle

Purge the Infection. Rule the Ruins. The initial outbreak was just a cough; the "Carrion Protocol" is the extinction event. With the Apex Survivor Bundle, you aren’t just a scavenger—you are the apex predator of a rotting world. This pass grants you priority access to every major containment breach, bio-engineered mutation, and chemical prototype at a significant ration discount.

Containment Breaches (The Campaign Expansions)
  • The Marrow Orchard: Venture into the "Overgrowth Zone," a forest of calcified bone where a hive-mind fungus has begun to mimic human speech. The spores are blooming in the lungs of the dead, and they recognize your scent.

  • Neuro-Toxin Pulse: A strain of "Grey-Brain" is liquefying the cognitive functions of the remaining bunkers. Race to the underground bio-labs to synthesize a cure before the last of humanity loses the ability to remember how to breathe.

  • The Scavenger Royalty: Navigate the brutal tribalism of the wasteland warlords. A scorched-earth war has erupted between a feral cannibal cult, a high-tech corporate remnant, and a mutated super-colony. Which throne will you build from the scrap?

āš™ļø Bio-Engineered Augments & Chem-Tech
  • The Stalker’s Kit (Utility DLC): A collection of "Pre-Collapse" gear designed for absolute urban stealth. Includes the "Chameleon-Skin" Ghillie, the "Ferro-Fluid" Lockbreaker, and Padded Sole-Wraps for silent movement across shattered glass.

  • Dead-Zone Armory (Weapons DLC): Brutal weaponry forged from industrial scrap and caustic chemicals. Features the "Spine-Ripper" Harpoon Gun, the "Acid-Etch" Serrated Blade, and the "Blight-Fire" Incendiary Launcher.
