Fortnite is a 3D action third-person game that involves up to 100 players who descend on the map. After that, they look for equipment and weapons. The goal of the game is to eliminate other participants and remain the only one (or the only team) alive. The available safe area on the in-game map starts decreasing over time, making the available space less and less over time. Such kind of game is named ‘Battle Royal’ (from a Japanese classic movie). The main difference between Fortnite and other Battle Royals is the building option. A player can put walls and other elements to protect themselves at any moment. The last surviving player (or team) wins the round. The game provides a single-mode, as well as a game mode for teams from 2 to 4 players.
