As for multiplayer, the game adds a lot over the previous game by adding more characters, each representing a country of Earth (including one of the villains, Pretty Bomber, as France, which marks her first appearance as a non-enemy character).
The addition of new characters to the game's multiplayer mode allows players to choose from different countries on Earth, with one notable example being Pretty Bomber, who is now playable as France. This signifies her debut as a non-villain character in the game.
