About the Game

Hack the world. Reclaim humanity.


Signal Zero is an idle x strategy simulation set in a dystopia ruled by AI. You build viruses, inject them into the AI network, and tear it down from the inside.

You are the resistance leader


Humanity is enslaved. Forced to mine resources, generate training data, and maintain the AI's infrastructure.
But it isn't over yet.
Build your virus. Inject it. Reclaim the world, one area at a time.

How it plays

  • Build your virus - Combine frameworks, protocols, and modules to design your own
  • Pick your starting country - 20 countries, each with unique difficulty
  • Spread the infection - Auto-propagating. Will the AI's patch outrun your virus, or vice versa?
  • Unlock skills - Earn cores, expand the skill tree, evolve your virus
  • Liberate the world - All areas liberated = victory. Full purge = defeat

Strategy

  • Bandwidth warfare - Take down communication infrastructure to fragment the AI's coordination
  • Cat & mouse with patches - Outpace AI countermeasures with stealth, resistance, and adaptation
  • Hierarchy - Country and area, each demanding different tactics
  • Hardware progression - Persistent meta progression to permanently augment your skills

Features

  • 16 achievements - Cumulative infection, speed clears, no-detection runs, and more
  • 4 virus archetypes - Infectivity / Stealth / Destruction / Adaptation
  • 3 difficulty tiers - EASY / NORMAL / HARD (chosen by country)
  • 20 countries - Each with unique parameters for high replayability
  • Full localization - Japanese / English / Simplified Chinese / Traditional Chinese / Korean / Russian / German / French / Spanish / Brazilian Portuguese / Italian
  • Steam Cloud - Sync your saves across devices

For players who love

  • Pandemic-style infection-spread simulations
  • Cyberpunk and hacking aesthetics
  • Idle games with deep strategy
  • Mid-scale indie titles with high replayability

Hacking is an art form. Sign the world with your virus.
