The latest “Pokemon” game to come to Nintendo 3DS, “Pokemon Super Mystery Dungeon,” is coming to the U.S. in 2016. To make things enticing, The Pokemon Company International shared to Nintendo Insider last week that fans will be able to see all 720 Pokemon characters -- giving it one of the largest video game casts ever seen on a “Pokemon Mystery Dungeon” game.

But Nintendo Insider said only 20 of the Pokemon are playable characters. These include fan favorites, such as Pikachu and the original three starters: Bulbasaur, Charmander and Squirtle. Players will also have encounters with some of the newer Pokemon, as well as older, legendary Pokemon, such as Lugia from “Pokemon Silver.”

“Pokemon Super Mystery Dungeon” is the latest installment in the popular “Pokemon Mystery Dungeon” series that started in 2005, with installments on the Gameboy Advance and the original Nintendo DS. As of 2013, there have been nine Pokemon spin-off titles, with “Super Mystery Dungeon” being the 10th entry.

Nintendo revealed that all 720 Pokemon would be in the game during the Japanese-only Nintendo Direct presentation, as reported by Siliconera. Prior to this, previous reports said this title would be “even greater” than the other games in the franchise.

The game seems to have the same story as the other games in the series, with the player waking up one day and finding out that he or she has been turned into a Pokemon. As the game goes on, players recruit other Pokemon in their party as they explore dungeons and engage in plenty of “roguelike” gameplay, including exploring dungeons and engaging in turn-based combat that gives the players options to use regular attacks or Pokemon attacks.

“Pokemon Super Mystery Dungeon” is an exclusive title to Nintendo 3DS and will be out in Japan on Sept. 17. The game will come to Western shores sometime in early 2016.
