Nights of Kronos in Sonic 06??

[Neerb]

On the 360, there is a Sonic 06 achievement called "Nights of Kronos" that says "Unlock the complete ending to the last hidden story."  I've beaten the hidden ending (the one you get after beating Sonic, Shadow, and Silver's stories) and I still haven't gotten this achievement, so how do I unlock this "secret ending?"

Maybe ur 360 is just messed up...
That is the final ending when you beat Solaris (single dumbest Super Sonic fight in history, just hold Shadow's chaos spear and you win X_X )

How can this be the cause of a mess-up?  I got another achievement for beating the last story, but there's another one waiting for me to get (nights of kronos) that says there's a hidden final ending!  A glitch wouldn't create a new Achievement with a name and description...

Sorry, but there isn't any secret "final" ending.
Beating Solaris is the end of the game. Sorry. It's probably a misprint or something...
