USA-OS NOTICE

WIDE SCREEN REQUIRED

USA-OS America 250 is designed for a command center with a wide screen and way too many blinking numbers.

Please open this on a larger display for the full 8-bit America OS experience. Touch screens are supported when there is enough room.

USA-OS HELP

How to Play

  1. Click DO WORK to create CPU cycles.
  2. Click SHIP PROGRESS to convert stored cycles into National Progress.
  3. Spend Progress on repeatable Systems: Innovation makes cycles, Infrastructure ships progress, and Institutions reduce instability while building Civic Capacity.
  4. Install Policies for one-time upgrades that specialize the economy.
  5. Advance History to unlock eras, new systems, and stronger upgrades. Civic Capacity lowers future History costs with a capped discount.
  6. Keep System Balance healthy. If Instability reaches 100%, USA-OS crashes and the timeline ends.
  7. Unlock medals by hitting major milestones. The Freedom Eagle will let you know.
