Fortnite is a 3D action third-person game that involves up to 100 players who descent 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 games named ‘Battle Royal’ (from Japanese classic movie). The main difference between Fortnite and other Battle Royals is the building option. 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 in teams from 2 to 4 players.
