Fans of role playing games are most likely very familiar with an Action Point battle system. Each attack or ability uses up a specific number of APs, with the APs recharging a certain amount per turn. Final Fantasy: The 4 Heroes of Light uses this system. It's been a while since we've seen anything from the game and the AP system is not at all confusing; however, we have a video today that explains it. There should be more information for Final Fantasy: The 4 Heroes of Light in the coming weeks, too. It will be released on October 5 for the Nintendo DS.
