A solid storyline, the inclusion of co-op play and plenty of unlockable items and abilities go a long way in extending the life of this game. However, the contradictory AI and sometimes abysmal camera angles can complicate the gaming experience.
Even without the open-ended level design, it was every bit as absorbing as the first game was at its very best and then some. And because of its mission-based structure that allows for quick access to all unlocked levels, it became a very hard game to put down.
Good graphics, solid controls, decent sound (including purposefully-campy English dialogue) and mucho replayability (especially from its two-player mode) make Wrath of Heaven the best Tenchu game of the trilogy.
The story is confusing and as far as I'm concerned you might as well forget trying to figure out the whole picture. Just concentrate on completing your current mission and everything will take care of itself.
The graphics aren't particularly innovative and the sound effects are merely a step up from mediocre. However, Wrath of Heaven succeeds where it counts - in providing an enjoyable experience with plenty of replayability.
The control is satisfyingly tight and responsive, and the stealth kills (spookily augmented by the controller's vibration function) are right on that clinical line between gratifying and, well, a bit disturbing.
