From top to bottom, Tenchu Z is a disappointment. No matter what aspect of the game you look at, there's a fatal flaw. There are 50 missions, but most of them are the same. You can sneak around, find creative ways to get to your objective, use a large number of interesting weapons, and kill bad guys with the press of a button, but you don't need to because you can simply run or summersault right past everyone. You can extract some fun out of the experience if you use your imagination and approach each level like a ninja, but unless you really, really want to kill some ninjas, you shouldn't waste time and energy trying to make this game fun. The developer certainly didn't.
