It also has Samurai Shodown and Metal Slug in it
A rhyhthm game based on various franchises from the SNK world (most notably King of Fighters) is a thing, and it’s dropping on iOS and Android this week. The base app is $0.99, with extra songs available via in-app-purchasing (mobile DLC).
Characters can level up, as well as call upon support while they’re battling it out by way of a rhythm based interface. User reviews seem to be pretty positive (assuming they’re not fixed), and I’ll be giving my thoughts on the game fairly soon.
