Killer Dogs
Once on the atttack, these German shepards will move directly towards their prey. A single bullet will bring down a killer dog. However, they are trained to quickly dodge during an attack, making them difficult to shoot. Besides being somewhat of a nuisance, the Nazis effectlvely use them as a cannon fodder. Don't waste your bullets on dogs untill they are at close range. It is easier to kill dogs if you stand in a doorway and wait for them.
Guards
Guards are the grist for the Nazi mill, but can be and effective force if fighting in groups. They wear no body armor and can be brought down in a single shot. Carrying only a pistol, their firepower isn't exactly menacing. Guards are slow to react and must stop and take aim before shooting, making them particularly vulnerable to a machinegun attack. Using the chaingun on these fellows is really a waste of good lead.
SS
The SS are well-trained and can rarely be surprised. Most will bark a warning when they become aware of your presence. This can make for an easy head count. However, some are trained to be silent. Wearing bullet proof vests and carrying a machinegun, the SS are difficult to bring down and pack a heavy punch. If an SS shoots you at close range, the encounter will be brief because you'll be toast!
Mutants
Mutants don't make a sound until they shoot, greeting you only with the crack of gunfire. They are extremly aggressive and will continue to attack until dead. Mutants are equipped with chest guns and cleavers. They wear no armor, but can take almost as much damage as an SS guard.
Officers
Officers are usuall silent until they confront you face to face. They can rarely be surprised, and are fast, intelligent fighters. Officers will move to the left and right as they fire, making them difficult to hit aswell as draining you of ammunition. An officer's weapon of choice is a pistol. They wear light vests and can take abount half the damage of an SS guard. Don't underestimate their abilities. In close quarters combat, these guys will make life miserable and short.
The Bosses:
Hans Grösse
Guarding the exit to castle is one Hans Grösse. He comes from a large family with one sister, Gretel, and many brothers. Watch out for them in future levels" Hans is big, but he is not very smart. Shoot at him, strafe to the side when he's about to shoot, then have at him again! Soon he'll be crying "Mutti!" ("Mommy!") and you'll be running for freedom!
Dr. Schabbs
Dr. Schabbs has created an army of undead fighting machines, and now he wants you to join their forces! Armed with hypos full of his poisonous corpsokinetic animation serum, he's mean, obscene, and wants you to be green!
Adolf Hitler
Adolf appears in three guises here. The first is a dummy in scary black robes, flown around on wires, with a flamethrower mounted in its chest. As you dispatch these, they fall to the ground and you can hear Adolf's mocking laugh. Once you make your way past all the Fake Hitlers, you meet up with Adolf in steel, motor-assisted battle armor, with four fast chainguns. If you manage to knock him out of this death armor, he pops out fast and firing two normal chainguns. He's hard to run away from! Keep scooping ammo and health and firing at him. Eventualy, he will fall under the heat of your righteous bullets! The free world is saved from hateful tyranny! Long die Hitler!
Otto Giftmacher
Giftmacher (whose name means "poison maker") is responsible for the cemical weapons. But when he needs to waste that rude intruder, Otto turns to his close-range offensive weapon of choice-a mini-missile launcher!
