The initial set of 20 playable creatures has now surpassed the number 40, and many more Pokémons are expected to be added in near future. Since the game receives regular content and gameplay updates, the initial roster of accessible Pokémons was drastically increased in the first year of the game on the market. The key to victory in many matches will hide in special moves that all Pokémons can perform, as well as the tactical use of powerful 'Unite Moves'.
Players start the game with a weak selection of Pokémons, but they can dramatically upgrade their offensive and defensive capabilities by winning training and online matches, knocking opposing Pokémons, capturing wild Pokémons, and more. In addition to this central mode, the game also offers many other side activities, including timed maps, Quick Battle (which limits the number of players and reduced the match size to 5 minutes, and more. The main multiplayer mode of this game revolves around the battle arena that houses two teams of 5 players, who can fight against each other until one team wins or some team surrenders. While the traditional mainline Pokémon games allow players to slowly build up their collection of Pokémon creatures by exploring the open world and upgrading them via various combat challenges, Pokémon UNITE was developed from the ground up to be focused only on combat arenas.
