This game is the best arcade game ever made.  When I go to the arcade I shovel out quarters to play it.  I have never beaten it though and I don't know how many levels there are.  You are a guy who is carrying around an axe or sword and you hack at baddies as they move into the screen.  Some enemies are more powerful than others and it takes longer to kill them.  If you knock a guy off of his lizard then you can jump on it and ride it around slashing at the baddies.  The graphics are also very good.  You should buy this, no, you must buy this.  It is essential in order to survive.  It aint no lie, Buy Buy Buy!!!
