Wolfenstein 3D Classic puts you in the boots of soldier William "B.J." Blazkowicz; you must fight your way through six different episodes each with eight levels and a secret level. You're armed with a variety of weapons to battle the Nazi soldiers, undead mutants, and other foes. Each episode culminates with a boss battle. To help you along the way you'll pick up ammunition for your weapons and first aid kits and food to restore your health. There is also treasure to collect and secrets to uncover. Four difficulty levels provide additional replay value.
