Since this is a Tri-Ace game it should come as no surprise that Infinite Undiscovery has a real time combat system. However, you don’t shift into battle mode like in Star Ocean 3. All the action, exploration and combat takes place on the field.
Infinite Undiscovery also has situational battles where you fight in a dynamic environment. In one battle an ogre is chasing you down and the environment changes in real time when you react to the ogre. Another fight has players surrounded by gigantic tidal waves. This system sounds like it has potential to offer something new, if Tri-Ace extends the situational battle system beyond boss fights.
