Dead Head Fred review at IGN.

"Life sometimes isn't particularly fair, especially when it starts throwing a ton of curveballs your way. Imagine that your best friend moves from a reliable business partner to a raging alcoholic. Your girlfriend's father, who just happens to the one of the leaders of your town, mysteriously vanishes. Even worse, when you try to investigate his disappearance, you find yourself at the top of a mobster's hit list, with a bad case of amnesia and a jar for a head. It's enough to make you rail against the world and the inhabitants of your town for such a raw deal. That's the basic premise behind Vicious Cycle and D3 Publisher of America's twisted noir action game Dead Head Fred, one of the most creative and enjoyable titles to come to the PSP."
