Unlike another recent ninja title, Activision's excellent Tenchu: Stealth Assassins, Eidos's Ninja: Shadow of Darkness makes no attempt at strategy; rather, it is an arcade-style beat-em-up that harks back to such relics as Double Dragon or Streets of Rage. Although the graphics are three-dimensional, the play mechanics remain roughly the same (walk right, kick the snot out of a couple of guys, walk right...)
