Alternate ending...

Okay, so I read everyone if you complete the Stallatio Quest, gain Cinna's Hamer from Hades and keep it in your equipment, you get an alternate ending.

My question here is, is the whole ending changed, are there some extra parts added. What exacle does it do? Cause I wanna see the ending, but I don't know if have to complete the game two or one time to see everything!

And no spoilers please, I want to keep it a suprise :)

It simply adds a single extra scene. Nothing to get too excited about, since it's not very important, but a nice addition, all the same.

Right - its a brief extra scene involving the Tantalus gang - its not FMV or anything, but a nice little addition all the same.
