I just came across this today, and couldn't find anything on the global fansites about it yet.

The instructions to the Series 2 "Quest for Energon" Dark Energon Blaster that Hasbro promised but never put up on their American site, have apparently been released on the Hasbro Taiwan site (of all places) -

And mirrored at the Kreo Wikia site only a week ago (which is where I found it) -
Instructions Quest Blaster - Kre-O Wiki (this is the better link to click on if you want smaller images that don't take a while to load up)

The images are mirrored at several sizes, if you click on the "view photo details" links at the bottom of each image, or click on the images for the largest size of each.
