Hypershot is a render software. Models can be imported as obj along with the texmap (and maybe the bumpmap too, but not sure) done with Sculptris.
Aces High is the Iron Maiden's song and Eddie is portrayed in the single's cover (correct me you Iron Maiden's fans or give me Hell! ). Eddie the Head is the band's pet just like as Vic Rattlehead from Megadeth (which is also a pretty nice character to model, maybe later).
