If this 3-D game doesn't get your adrenaline pumping, nothing will. Zero Tolerance has you killing alien terrorists who want to annihilate your defense colony. But don't worry, you have an arsenal of weapons to hunt them down through a maze of passageways, hidden doors and gunfire. Zero Tolerance is heart-pounding, non-stop action as you take-out the bad guys with grenades, shotguns, bazookas and laserguns. And it's all in a 3-D, 360-degree perspective. Zero Tolerance. You don't just play it, you survive it.

Battle several enemies at once through dozens of levels. Realistic sounds heighten the suspense.

Ground breaking behind-the-gun first person perspective-the first of its kind for the Sega Genesis.
