Where to buy Cyberphobia: Prologue - Expansion Pass 25 at the best price? As of 9 Nov 2026 this title has one offer, $199.99 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 $199.99 today, which puts the pair at $399.98. 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 25

Cyberphobia: Prologue - Expansion Pass 25 - about the game
Neon & Null: The Logic-Gate Breach – Root Admin’s Source Code

Sync the Neural-Link. Overwrite the Grid. The era of flesh has been deleted; the "Logic-Gate Breach" is a flickering, high-voltage rebirth. With the Root Admin’s Source Code, you aren't just a user—you are the architect of the simulation. This override grants immediate bandwidth-priority for every sector-wide virus, experimental avatar-shell, and digital-miracle at a significant memory-byte discount.

The Fragmented Archives (Campaign Expansions)
  • The Silicon Ossuary: Dive into the "Buffer-Overflow Sub-Levels," a distorted network of fiber-optics where discarded security sub-routines have developed a predatory sentience. The static in the audio-feed isn't lag—it’s the code rewriting your identity.

  • The Pixel-Rot Plague: A cascading wave of "Frame-Rate Decay" is freezing the inhabitants into jagged, low-resolution statues. You must reach the Kernel-Core to force a system-reboot before the entire simulation is wiped from the drive.

  • The Sapphire Syndicate: Infiltrate the encrypted firewalls of the Data-Lords. A three-way proxy war has erupted between a radical "Open-Source" cult, a fleet of high-speed packet-interceptors, and a sentient, gold-plated cryptographic mainframe. Will you patch the vulnerability or crash the server?

⚙️ Exploit Kits & Malware Hardware
  • The Infiltrator’s Script-Bag (Utility Expansion): A suite of "Zero-Day" exploits designed for total systemic subversion. Includes the Binary Distraction-Smoke, the Logic-Bomb Breach-Tool, and Pixel-Dampened Gravity Boots for soundless navigation of the source-walls.

  • Overclocked Hardware (Weapons Expansion): High-frequency destruction for the virtual enforcer. Features the Plasma-Bolt Rail-Pistol, the Mono-Filament Laser-Scythe, and the Voltage-Spike Fragment-Grenade.
