In Once Human, players can use vastly different builds in order to increase their damage output or survivability in the hostile world of Nalcott, such as the Fortress Warfar Tank build. One of the main progressions of the game is crafting higher tiers of weapons and armor, as well as upgrading the blueprints that create them. Using blueprints for different gear sets gives players unique buffs to increase damage based on the weapon type they have chosen.
