On October 27, a fax was received at AFAO.com, listing a number of US cities. Over the following days it was updated with specific coordinates and instructions for retrieving packages at those locations. AFAO also linked to Metastasis, where a 'game' of sorts allowed people to experiment on viral samples. Those who retrieved packages also found subject numbers which unlocked additional test cases for experimentation. Once any test case was solved, a new document would be unlocked.
