Fallout 4 is an open-world action role-playing game developed by Bethesda Softworks that was released in 2015. In the game, players assume the role of the Sole Survivor who emerges from a nuclear bomb shelter after 200 years to search for their kidnapped son Shaun in the wasteland of Boston. The game features both first and third person perspectives and allows players to explore the open world and complete quests at their own pace. It also introduces base-building as a new gameplay element where players can construct settlements. While praised for its expansive world, character customization, and story, it also received some criticism for bugs and issues with companion AI.
