Spotlighted in tonight's Rockman Online blog update: Blues! Yes, like many classic series characters before him, the bot with the shades has been resurrected and he's looking as sharp as ever.
While there is no confirmation that Blues will be among RMO's playable characters, the blog does seem to imply that he will at least be a very important character when it comes to plot. Shame, really, because I'd love to play as that. ---->
Anyway... nothing hugely major mentioned over at the blog. Just a recap of Blues' history: his conception, his faulty core, etc. Nothing new, really.
Of course, this is based off of an initial translation. There might be a few more striking details I might have missed, but we shall find out soon enough I'm sure.
UPDATE: As anticipated, more details. Hit up The Mega Man Network for the full scoop
