Fortnite is a co-op sandbox survival game, developed by Epic Games. The focus of the game is on exploration, scavenging items, crafting weapons, building shelters, and fighting encroaching monsters.
Building is a core element of the game, where players build their fort on a 3×3 grid by creating walls, windows and roofs to suit their needs. Players must work together to scavenge items they can use for building, and defend their structures from their opponents, the Husks.
Maps and terrain are randomly generated and players are initially given a variety of weapons, such as pistols and rifles. Players can also create their own weapons, improving their level in the game. Fortnite additionally has a player-versus-player mode, which can support up to 10 players at one time.
