Daniel X is one of the greatest superheroes ever to walk planet Earth. He has defeated a host of evildoers on The List of Alien Outlaws, and now he’s ready to raise the stakes on his next impossible mission – by eliminating a pair of sadistic shape-shifters at the helm of a massive videogame enterprise.
Their next addictive game release, Crown of Thorns V, is about to control the minds of kids all over the world!
