Once Human is setting itself up to be one of the biggest free-to-play survival games, featuring a vast open world where players can build their own territory and scavenge for resources and items to boost their survivability. While most players will focus on grabbing the essentials like food and water, along with crafting the most basic weapons and equipment, players looking to take on the toughest Monolith bosses will need to get their hands on some of the best weapons in the game.
