The Field Ops Log is a soldier's patrol record inside the Goldstone Building, the tilted skyscraper downtown. Climb the stairwell toward the fifth floor; it lies beside the second dead soldier, along with a couple of 9mm rounds.
A FEDRA squad arrives in July 2033 and logs hour after hour of nothing, with growing frustration. Then a private reports stage-two infected near this collapsed office building and the squad moves in to check.
Within half an hour they are overrun. Three privates are listed as killed, and the survivors fall back inside to wait for an evacuation. Joel notes that they died waiting for help that never came.
Lenz's Firefly Pendant
Lenz's Firefly pendant dangles from a tree on the terrace outside the Goldstone Building in the Downtown section of The Outskirts. It belonged to Joseph Lenz and must be knocked down.
Davidson's Firefly Pendant
Davidson's Firefly pendant lies underwater in a stone rotunda in The Capitol Building section of The Outskirts. It belonged to Melinda Davidson and is easy to swim past.
Evacuation Leaflet
The Evacuation Leaflet is an old FEDRA warning on the right-hand pavement in downtown Boston. Once you climb the collapsed street and Tess and Ellie start talking about the bombing, look by the base of a traffic light a car has hit.
Firefly Map
The Firefly Map is a note on a dead Firefly in the subway station downtown, on the stairs between the two escalators. It is the body to the right of the one carrying a Molotov cocktail.
