A remastered ("all-new graphics and visual effects in widescreen format," says Sega) version is coming to XBLA this fall with online co-op and battle modes, and a few others.
This is exactly what I've wanted on XBLA for a few reasons. Obviously, I'd like to play the game for much cheaper than the Saturn price. It also might be the start of more Saturn games getting the treatment, which would be amazing (Radiant Silvergun got an announcement I remember, but I can't think of any others yet.) And, just a continuation of more beat-em-ups for my consumption. More beat-em-ups and fighters please. Let me punch shit! Cool decision, Treasure/Sega.
