ZeroTolerance writes: If there is one thing that the PSP is lacking, it is an abundance of mindless action games designed for attention-deficit gaming. Most hardcore gamers are certainly aware of developer Irem and their classic franchises such as R-Type, Lode Runner and Moon Patrol, but they also created a twisted side-scroller that revolved around beating things down with an oversized hammer. Hammerin' Hero is the spiritual successor to Hammerin' Harry, and it delivers just the type of gameplay experience that PSP owners are usually denied. Like Prinny before it, Hammerin' Hero is just the type of mindless beatdown that PSP owners have been clamoring for, but along with the old-school mechanics, come the unforgiving difficulty.
