From 3D Realms:
In Shadow Warrior, you play the part of Lo Wang, a master ninja who has vowed to avenge a long-ago disgrace. At your disposal is a vast array of weapons and skills to assist you in your bloody quest, including lightning-fast martial arts punches, triple shurikens, riot guns, single or double uzis, rocket launchers, grenade launchers that fire bouncy projectiles, and bombs that stick to their targets. Shadow Warrior features stunning 3D graphics and nonstop gameplay. The shareware version allows you to play the first four levels of the game.
