Would be grateful if anyone knows how to get this companion , the silver skull.
If I'm not mistaken the one you are talking about was available only at the E3 space a few months ago. I don't think you can get it otherwise.
Yes the silver skull companion was an E3 reward from back in June of this year. There was a gold skull companion available to purchase also, but it may have been for a limited time only. The skulls were both from Codeglue. You can always check the store for the gold one.
I just took a look, you can get the gold one if you're interested. Its under: Sidekicks*A-Z*Codeglue
The Silver Skull was a limited time reward at E3 2012
Description: Always wanted a skull for a companion? Now you can! Watch it do cool tricks and motions! This Mayan is available in silver and gold!
There is a gold one which is still available in Sidekicks for $2.49 in the Codeglue.B.V. Tab.
Yep E3 once a year thing. And something different each year!
Wonder what E3 2013 will have?
Maybe a FREE Super SLIM PS3 for Home so we can put it in our Apt's....
