Essentially what this game is a portable version of Tenchu Wrath of Heaven. The third major entry from the Tenchu franchise that debuted on the PS2 back in 2003. All the sneaking thrills and silent kills have been faithfully translated on to the PSP with even the bonus items and stages that were added to the 2004 Xbox port included. Being on the PSP does have its quirks. For example, all the multiplayer modes have been scrapped. The visual fidelity has drastically been toned down to make it run on the portable. And the most obvious of them all, the controls take getting used to. Apart from those issues, Tenchu Wrath of Heaven is an all time fan favorite and getting to play its entire campaign on the go is a very sweet deal. It is an import-only title but the anguage barrier is not much of a problem if you are accustomed to Tenchu titles.
