Grog

Grog is a game where Andrew and Isaac go to Rome.  There they meet a huge beastlike creature (Luke). He calls himself "Grog".  In an epic battle, Andrew and Isaac chase him all across Rome, causing huge destruction.  Eventually Grog rams Andrew and Isaac into a huge sewer, where there is nuclear reaction going on.  There they get super powers and easily destroy Grog, but this is not the end, because they have a new enemy to face: The super ultra villain.
