The Massachusetts State House, usually called the Capitol Building in the game, is where Marlene sends Joel and Tess to hand Ellie to a waiting Firefly group. It is the goal of The Outskirts and gives the chapter's last section its name.
Robert sold weapons meant for Joel and Tess to the Fireflies. Marlene offers them back if the pair escort Ellie across downtown to the State House. FEDRA, though, has been cracking down on Fireflies both inside and outside the zone.
Soldiers found the Firefly group first and killed all of them. Tess then shows Joel she was bitten in the museum, asks him to take Ellie to Tommy, and stays behind to hold off arriving soldiers. She kills two before they shoot her.
Freedom Museum of Boston
The Freedom Museum of Boston is a history museum about the American Revolutionary War that Joel, Tess and Ellie cut through in the Museum section of The Outskirts. A wave of infected chases them inside, and you fight clickers and runners through its exhibits.
Boston slums
The Boston slums, marked Area 5 on military maps, are the poor district of the Boston quarantine zone where the smugglers run an open black market. You walk through them in The Slums section of The Quarantine Zone while hunting the smuggler Robert.
Quarantine zone
Quarantine zones are the walled, military-run safe areas FEDRA set up across the United States after martial law was declared. Most have since fallen to infection, revolt or abandonment. Boston's North End zone is the one you live in and play through at the start of Part I, and you pass the dead zones of Pittsburgh and Salt Lake City later.
The Goldstone Building
The Goldstone Building is a damaged downtown Boston skyscraper that Joel, Tess and Ellie climb through in the Downtown section of The Outskirts, because a chasm blocks the street. It is packed with infected, including stalkers, runners and clickers.
