East Boston appears only in Fallout 4.
- Fallout 4 Vault Dweller's Survival Guide Collector's Edition pp. 324-325: "ZONE 4: COASTAL COMMONWEALTH
Those hoping to vacation on the eastern shores of the Commonwealth would do well to pack a copious supply of ammunition and have trained long and hard for this outing, as the threat level of the roaming miscreants in this zone is deemed “most dangerous.” The township of Revere has been razed by Raiders. Nahant offers quiet walks interspersed with carnage, courtesy of ferals. Up north, Salem long continues its reputation for horror. Farther inland, toward East Boston and the airport, the ferociousness of your foes lessens just a little. The Brotherhood of Steel's imminent arrival at the airport should provide a brief respite should you agree to ally with them. Finally, those brave to dip their toes in the ocean may find one or two surprises under the waves."
