Mamon King gets Nintendo Switch 2 edition with Gallery Mode on October 8, 2026

That Gallery Mode lets players view background art and listen to BGM. No other exclusive Switch 2 bonus is specifically mentioned in the available store information.

Mamon King is a monster-raising game where players train Mamons, monsters from another world, using a mix of kindness and discipline.

What happened

The Nintendo Store has put up a page for Mamon King for Nintendo Switch 2 with a planned release date of October 8, 2026. The page also says it is a special edition for Nintendo Switch 2. That gives the game an additional platform version alongside its existing releases on Steam, PlayStation 5, and Nintendo Switch.

As extra content, Nintendo lists a bonus Gallery Mode. According to the store text, players can use it to view background art and listen to BGM. The provided sources do not mention any other Switch 2-specific additions with the same level of detail. One external source does refer to “exclusive bonuses” in the plural, but the available snippet only spells out Gallery Mode.

Mamon King is about raising and training Mamons. In the product description, these creatures are described as monsters summoned from another world. The game focuses on a ranch-based raising system, Inheritance Summoning, and turn-based battles with unique abilities for each monster. The Steam description also says the power of a trained Mamon can be passed on through Inheritance Summoning, while the community description says the combat is easy to understand but still tactical thanks to unique skills and SP costs.

The available context also shows that Mamon King is already on other platforms, including Steam, PlayStation 5, and Nintendo Switch. The Switch 2 version therefore appears to be an additional release rather than the game’s first launch. The Nintendo Store page is the clearest source for the special edition and the Gallery Mode.

Background

Mamon King is described in store and promotional text as a monster-raising simulation on a ranch. Players train Mamons, use Inheritance Summoning, and build on the strength of previously trained monsters. The Steam text emphasizes that a Mamon’s potential grows through skill and luck, while the PlayStation Store uses the same basic description for the game.

The battles are turn-based and each monster has its own abilities. The available description also says SP is needed to activate those abilities, which makes the fights more strategic. The Steam community description adds that the combat is easy to grasp, but still tactical because of the combination of unique skills and SP.

According to the Nintendo Store, the Nintendo Switch 2 version adds a Gallery Mode. That feature is limited to background art and BGM, and the sources do not suggest that the content differs further from the existing versions on Steam, PlayStation 5, and Nintendo Switch. The available information does say the Switch 2 release is being presented as a special edition, but it does not specify any new gameplay systems or story elements.

The product descriptions present Mamon King as a game about building your own team by training monsters and passing on their traits through Inheritance Summoning. External context also says the game centers on a ranch-based raising system, with help from a shady scientist or a muscle-bound trainer in the Steam description. That makes it clear the title has long been positioned across multiple platforms as a monster-raising game with a strong training focus.
