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.
Joel and Tess pry a dead clicker off a wall to get into a room, and a live clicker jumps Joel until Tess shoots it. You pick up the Field ops log from Waters' body, fight through turned soldiers, then sneak past clickers in the shopping level before leaving for the State House.
FEDRA warned residents with leaflets, then bombed downtown to kill thousands of infected. The area became unlivable, the military gave up holding it, and the infected moved back in.
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.
Massachusetts State House
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.
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.
Liberty Gardens
Liberty Gardens is an abandoned two-level mall in Boston where Ellie and Riley spend a night together in Left Behind's flashback chapters. You explore it in Mallrats and Fun and Games, and it gives the final chapter, Escape from Liberty Gardens, its name.
