Fortnite is described as a co-op sandbox survival game and the exploration, recovery of objects, construction of fortified structures, and the fight against encroaching waves of monsters. Players will work together to collect items they can use to build a day to build their fort, and the night defend against zombies. Building will be a core mechanic in the game, and there will be “much booty” buried in. Players can build and edit each wall of their hard with a 3 × 3 grid, fix the stairs, roofs and windows sculpt to meet a particular need. Because of these gameplay elements, the game is described as “Minecraft meets Left 4 Dead” by Tim Sweeney, founder of Epic Games.
