A Dynamic WorldUsing 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.  Brutal Sandbox CombatExemplifying true, free-form gameplay, Days Gone offers freedom to explore, strategize and play “your way.” Every challenge can be approached and completed in an almost infinite number of ways. Many different items and wens can be crafted using items found in the field, including brutal melee wns and traps. Customizable weons and skills offer true freedom in how the game is played.  Unique EnemiesIn addition to human drifters, marauders, and other groups, Deacon must face a wilderness overrun by Freakers – mindless, feral creatures, more animal than human but very much alive and quickly evolving. Freakers have needs, habits and behaviors that the player can learn and adapt to.  Unique SettingThe harsh high-desert of the Pacific Northwest offers a large variety of environments in a single geographical area. One minute Deacon can be riding through a pristine forest, a snow field, a lush meadow, and the next, be in the harsh desert lava fields. The hazardous environments, scarred by millions of years of volcanic activity, are defined by ancient lava flows, mountains, caves, cliffs and river basins, delivering a breathtaking backdrop to an equally diverse style of gameplay. Cinnabar mines, lava tube caves and small rural towns offer a variety of environments to explore.Days Gone is an action-adventure survival horror video game developed by SIE Bend Studio and published by Sony Interactive Entertainment for PlayStation 4 on April 26, 2019. Set in a post-apocalyptic Oregon two years after a global pandemic, former outlaw-turned-drifter Deacon St. John discovers the possibility of his wife Sarah still being alive, which leads Deacon on a quest to find her. Days Gone is played from a third-person perspective, in which the player can explore an open world environment. Players can use firms, melee weons and improvised weans, and can use stealth to defend against hostile humans and cannibalistic creatures known as Freakers. A major game mechanic is Deacon's drifter bike, which is used as the player's primary mode of transportation as well as mobile inventory.Production of Days Gone began in early 2015. Technical director Christopher Reese stated that Bend Studio wanted it to "push the PS4 somewhere it's never been before. The game was first revealed by Sony at their E3 2016 panel. It was then announced by Reese the game would utilize Unreal Engine 4 and would have "a very strong narrative". The score was composed by Nathan Whitehead.Widely anticipated and slated for a 2018 launch, Days Gone was delayed several times and received mixed reviews from critics, who praised the open world, gameplay and Sam Witwer's performance as Deacon, although the story and lack of character development was criticized.
