A game which is in no way related to the hit Playstation 2 title is being created for the Game Boy Advance.
There are 2 "Oni" games in existance. One was created by Bungie, and was a huge PS2 hit. Another is an adventure game that was out in Japan and created by a different company. A company called Pandora Box is creating an Oni game based on the latter series for the Game Boy Advance. Apparently, Pandora Box also made an Oni prequel for the PSX called "Oni Zero: Resurrection." Nothing is known about the GBA title currently, other than the fact that it is not affiliated with the Bungie game Oni for the PS2.
