Fallout 4 is a continuation of the famous post-apocalyptic series, the events of which develop several years after the end of Fallout 3. The protagonist of the game is the only survivor of Vault 111, which was located near Boston. By the will of fate, the main character will have to leave his home to embark on an adventure full of dangers, where mutants, raiders, mercenaries and various natural hazards will stand in his way.

The fourth part of the series differs from its predecessors in a new location - Boston and its environs - as well as small changes in the game mechanics. Thus, the role-playing system S.P.E.C.I.A.L. was redesigned, the protagonist learned to modify weapons, as well as rebuild settlements destroyed by war. Power armor, the symbol of the game, is no longer a panacea for all ills - its wearing requires the presence of nuclear batteries. The dialogue system has also been reworked - in the fourth part, most of the tasks can be completed without engaging in battles with characters.
