A downloadable game for Windows

Blacksite Idle is a strategic idle game about building a covert intelligence operation from nothing.

You start with a single basement operation and limited resources. Through surveillance, field missions, agent management, and long-term planning, you expand into a global black-ops network that runs whether you're actively clicking or letting the system work on its own.

Missions are the core of progression. Each operation requires the right agents, skills, and preparation, rewarding Intel, experience, and permanent advantages that carry forward between runs. As your clearance increases, new systems unlock — agents can be trained, facilities constructed, and powerful long-term upgrades earned.

This is a free public beta of the full game. Everything is unlocked — full clearance progression, prestige, and all systems are open to play. It's released free while the game is in active development so players can experience the complete strategic loop and help shape where it goes next.

Key features

  • Active + idle Intel economy
  • Mission-driven progression
  • Agents with skills, archetypes, and training
  • Items and facilities with meaningful buffs
  • Clearance-based unlocks

This project is still in active development. Balance, pacing, and content will continue to evolve based on player feedback — bug reports and suggestions are welcome.
