We've already reported a Guardian Heroes XBLA release date once, which turned out to have been an error on the part of Microsoft's Major Nelson. Sega announced a new October 12 release date for the updated Saturn brawler today, and we hope it sticks this time.

Guardian Heroes will be available on XBLA for 800 Microsoft Points ($10). For those of you who got into Treasure games post-Saturn -- or, gasp, have yet to discover the rewards of the Treasure fanatic lifestyle -- you can get a glimpse of what you've been missing in the above trailer. And that trailer doesn't mention the 12-player online play.
