Using the power of PlayStation 4 and Unreal Engine 4, Days Gone offers an incredibly realistic and detailed open-world action game experience. Vast and hostile environments can be fully explored on the back of Deacon’s drifter bike. Abandoned vehicles can be searched for useful items. Towns and buildings can be entered and searched – at great risk. All lighting is done in real time – eye adaption technology creates a real sense of dread when entering dark buildings; day and night have an impact on the experience; weather affects enemy behavior.
