User Reviews More of the same (4 / 10) by The S Unreleased in the U.S., the upgraded version of Battle Spirit only showed up exclusively on the Wonderswan in the Land of the Rising Sun.
The game feels a bit more filled-out out than its predecessor, making all of the hidden characters (sans Impmon) initially available, and throwing in three new characters to tinker with: Patamon, Gatomon, and the hidden ExGuilmon. New stages also are present. However, it's really more like a director's cut of the original and really doesn't make too much of a difference in the game overall.
Millenniumon returns as the standard final boss, but now a personal favorite of mine is introduced as a hidden final boss, XeedMillenniumon. Incidentally, this was the character that, back when I was still heavily into the series, caused discord between myself and the rest of the fanbase to the point where I'm sadly an infamous legend around those parts (it's a long story). However, it's still a badass fight if you can reach it and is one of my top ten final boss battles in fighting games.
If you have access to a Wonderswan, it'd be best to just straight up pick up this and skip over the standard Battle Spirit, if you really want to play anything from this series. Hell, skip over Battle Spirit 2 while you're at it. As middling as this title is, it's still the cream of the crop in the series.
