Agent Gray: By now you are familiar with the unknown impostor programs who are attempting to impersonate our agents and, by attacking Zion operatives in that guise, disrupt our Truce with the humans. This must not be allowed. A group has been located in your vicinity. Destroy them all, and retrieve one of their PDA devices for analysis. Operator: I'm picking up very little foreign program activity inside--the impostor programs were supposed to be here, but the sensors don't indicate their signature in the area. Investigate and see if you can find any clues to their whereabouts.
