Fortnite is a co-op sandbox survival video game developed by People Can Fly and Epic Games, the latter of which also serves as publisher for the game. The game was released as a paid early access title on July 25, 2017 for Microsoft Windows, macOS, PlayStation 4 and Xbox One.
Fortnite is described as a co-op sandbox survival game and is about exploration, scavenging items, crafting weapons, building fortified structures, and fighting waves of encroaching monsters. Players will work together to scavenge items they can use for building, and defend their structures and objectives from the Husks. Building will be a core mechanic in the game, and there will be "a lot of loot" buried within. Players can build and edit each wall of their fort with a 3×3 grid, lay down stairs, roofs, and windows, sculpting them to suit a particular need. Due to this gameplay element, the game is described as "Minecraft meets Left 4 Dead" by Tim Sweeney, the founder of Epic Games.
