Mechanic Arms who are known for the Excave series (pictured) on 3DS as well as the Psycho Pigs remake amongst others have announced they will be publishing their first Nintendo Switch title in February. Going by Code Name ▲ (not the final name), and a 4-player action game, it has also been confirmed for worldwide release.
Mechanic Arms are releasing the third Excave game entitled Excave Unmei (which translates to something like Phantom Tower of Fate) on 28 January on the eShop for ¥500. The new hero is a female protagonist called Scarlett (no more boy). Go to http://www.mechanicarms.com/software/excave_unmei.html for more information.
