Game Arts' Grandia series has provided one of the most enjoyable battle systems in the genre. Grandia Xtreme, the upcoming third installment, will use basically the exact same engine as that found in 2000's Grandia II, but with the addition of the ability to perform combo attacks with party members.
The Japanese developer has recently divulged another addition to the gameplay experience. Upon completion of a dungeon, players will have the ability to return at any stage afterwards to forge their way through a beefed up version of the dungeon. Culling the nastier beasties will allow greater experience earnings and collection of special items as well.
Grandia Xtreme is currently slated to hit Japan on January 31. No specifics for North America are known at this time, but expect that to change in the very near future.
