Opus XI includes cards of many popular characters from various titles with its primary focus on Final Fantasy VII, which is slated for a remake. A new Counter mechanic will be implemented from this opus. These Counters will be placed on top of characters, and there will be various types such as Monster Counters and Shuriken Counters. Depending on whether the characters have a Counter or not, as well as the number of Counters collected, they will gain an ability, or their status will change. With the implementation of this new system, we look forward to seeing new game strategies from Opus XI onward.
