Square Enix is promoting the port with a crossover in another iOS title, Guardian Cross. Starting on March 26, players will be able to hunt Guardians from Final Fantasy V.

Hiroyuki Ito revolutionized Final Fantasy with the Active Time Battle system. Now, Ito is taking a stab at changing card battling games with Guardian Cross.

Square Enix’s mystery trademark was for a card battle game on iOS.

The publisher filed a trademark Guardian Cross in Europe and snapped up the domain name: guardiancross.net.
