Digimon World 4 is the second game in the Digimon series for the GameCube console. Instead of a standard RPG like the previous games, it has action RPG gameplay with hack-and-slash and supports up to four players. It also contains elements of digital pet games where creatures can be trained to level up. The game is loosely based on the events in the Digital Monster X-Evolution animated film. You can choose between Dorumon, Veemon, Guilmon, and Agumon as the playable characters. They are members of the Digital Security Guard and their mission is to save the DigiWorld from a computer virus, called X-virus, that invaded their world.
The Digimon can go through a digivolution based on a number of parameters. Magic skills are upgraded through training. There are several types of magic and each one has its own elements, type, and level. The game features three difficulty levels: medium, hard, and very hard.
