What makes "Fortnite Battle Royale" unique from other Battle royale games is the new building system, originating from the original Fortnite game. Players may destroy objects in their environment to provide materials so that they can build fortifications (walls, roofs, floors, etc) that help protect them from enemies. Some fortifications can be built quickly, but they will be destroyed easily. Some fortifications, however, can be built slowly but resists attacks better.
