Gameplay includes:
- a free open world with hundreds of locations to explore, a huge number of NPCs, companions and quests, as well as interaction with many factions, including the Institute, the Brotherhood of Steel, the Minutemen and Underground agents;
- SPECIAL! – a flexible character skill system with which you can create a killing machine or the best negotiator in the world;
- many unique territories: the remains of Boston, the Burnt Forests of the Commonwealth, abandoned cities, empty subway stations, etc.;
- VATS! – a precision aiming system created by the Vault-Tec company, which allows you to fire at certain areas of the enemy’s body in slow-mo mode;
- A rich crafting and base-building system, containing thousands of materials and items for building your own shelter, and subsequently an entire settlement. Crafting involves creating unique weapons or armor.
Among the companions is an available personal pet in the form of a faithful dog. As for companions of the opposite sex, you can build different relationships with each of them, even romantic ones. The inhabitant of the wasteland is free to go wherever he pleases. You can wander into radiation swamps, hear a radio signal from the local police station and respond to a distress call, witnessing a bloody massacre, thus starting a chain of mysterious quests. And this is just one of the few examples of random activities that the freedom and wide open spaces of Fallout 4 give.
