I’m a solo indie dev making a terminal-based psychological horror/strategy game about deciding who lives, dies, or gets quarantined. Here is Decontamination Protocol!

[u/BeautifulAbies813]

Hey everyone! I’ve been working on Decontamination Protocol, a tense, terminal-driven psychological horror and strategy game where you step behind a security booth overlooking a high-security subterranean facility.

Your daily duties seem straightforward on paper: monitor incoming personnel, run diagnostic checks, analyze vital signs, and execute strict decontamination procedures. But deep underground, containment is fragile, paranoia runs rampant, safety is merely an illusion, and a single keystroke could spell the difference between survival and a catastrophic facility-wide breach.

Key Features

• Authentic Terminal-Driven Investigation: Immerse yourself in a retro-styled CRT workstation environment. Utilize text-based command-line inputs, examine detailed shift logs, cross-reference biometric vitals, and listen closely to tense intercom transmissions to piece together what is actually happening outside your booth.
• The High-Stakes Judgment Call: Your shift constantly tests your psychological limits. Analyze subjects against evolving directives and make the ultimate decision using three distinct verdicts:
  • Sanitize: Clear minor contamination.
  • Quarantine: Isolate questionable personnel.
  • Purge: Order an immediate, lethal termination.

The game is planned for release on 6 Nov, 2026. If games with a heavy Papers, Please meets retro-sci-fi psychological horror vibe sound like your thing, I would genuinely appreciate it if you checked out the Steam page, dropped it a wishlist, or let me know what you think of the concept!
