Deacon St. John is living as a drifter with his old biker gang buddy, Boozer, in a world that has been reshaped by a global pandemic. The infected roam the earth, fast and ferocious, moving in packs and hordes, and have very little in common with zombies.
Deacon must navigate this new world, dealing with not only the infected but also human gangs and bandits who pose an even greater threat. The main storyline features several playable flashbacks that tell more about events before the pandemic, while side quests are presented as stories with their own progress trees. Days Gone takes place on the Playstation 4, where players control Deacon as he traverses a vast open world. The game's World Map is shrouded in darkness, revealing only visited locations and areas of interest such as refugee camps and NERO checkpoints.
The gameplay revolves around skills and upgrades, with Deacon earning experience points by killing infected or bandits, and performing quests. There are three skill trees: Melee, Ranged, and Survival, each with five tiers and three skills per tier to unlock.
Bike upgrades work differently, with settlements offering unique currency and trust levels. By selling ears collected from killed infected, players can earn credits in the settlement they sell it at, or by performing tasks for settlements to increase their trust level and earn more credits.
Combat is a key aspect of Days Gone , with Deacon able to carry four different weapons of various types. Each blunt weapon has its durability and strength, while pistols and small firearms are useful when other weapons are out of bullets. Machine guns and rifles offer a balance between accuracy and rate of fire, and sniper rifles pack the most damage. Scavenging is also essential to survive, with players needing to find materials such as empty glass bottles, gas cans, and specific branch types to craft items like molotovs and arrows. The motorcycle needs gas and repairs, which can be found in old gas stations or gas canisters.
As Deacon navigates this treacherous world, he must use his skills and upgrades to stay alive, taking down infected and bandits in a desperate bid for survival.
