Fortnite is a third-person action game focusing on cooperative gameplay. It was developed by the Polish division of Epic Games (formerly known as People Can Fly). The action of Fortnite takes place in a world haunted by zombie-like demons. The players assume the role of operators whose task is to stop the monsters that invade the Earth through a network of portals. The gameplay is divided into two phases — during the day, we have to build a stronghold that repels demon attacks at night. The gameplay mostly involves searching for materials, constructing fortifications, and fighting enemies. The game is distributed in free-to-play business model, offering some additional facilities for optional fee.
