It's all about Metal man
Basically it's about a roadie that gets transported to another world via some artifact which had some powers he wasn't aware of. The roadie voiced by Jack Black is basically a hero of legend destined to save humans from it's demonic overlords. The world is basically designed and given tribute to all the Heavy Metal environments and art that's been out there. It has a pretty good soundtrack if you are into some of the older metal and hard rock. Also it has some pretty big names as voice actors besides Black, you have Ozze, Leta Ford (iirc) and a few others I can't recall. It's a hack and slash style adventure game, there is some magic in the game that you can use with the help of an electric guitar (your other axe
). Also there are armies you get to control (a bit like Overlord). I have only rented it and not played too much as of yet but it seems fairly large.
