"An international crime of epic proportions has occurred. Members of a global crime ring, Baddies Against Rights & Freedom (B.A.R.F. for short), have hacked the most elite of institutions… the Bureau of Ideas! B.A.R.F. aims to destroy any and all files related to freedom, democracy, and rights. As Secret Agent 6, you will travel across time and the Atlantic world to investigate records that connect Enlightenment to the United States Declaration of Independence and beyond. Find how ideas have spread, track evidence of natural rights, state sovereignty, and the Social Contract, and restore the corrupted files. Game Features: - Multiple paths to completion: track Natural Rights, State Sovereignty, the Social Contract, or complete them all! - Explore 10 locations across the Atlantic world to collect evidence and connect. - Historical scenes enhanced by a narrative and rich material culture. - Mad-lib style activity links locations based on the evidence you collect along the way.
