Fighting games on mobile are a dime a dozen. The tactile feedback of a standard controller or joystick setup is absent on phones – barring any peripheral attachment. In lieu of that, developers have attempted many different approaches to bring the action of the genre to the device. Some go with swipe controls. Others give a digital button scheme an honest-to-God shot. But perhaps the most common and successful on the platform are card fighters.
Not to be confused with digital trading card games, card fighters usually feature a mash-up of simple taps of the touchscreen with a more direct use of specific attack and defense cards. These cards are tied to a constantly refilling energy meter, limiting how often you can use them. It’s simple, it in no shape or form even comes close to scratching the technicality of a traditional fighter, but relegating advanced moves to these cards does allow for some pretty breathtaking action. Case in point: Dragon Ball Legends.
