Soldiers - The G.G.G. uses troops of the Wehrmacht in its operations. They wear green field uniforms and bandoliers and possess basic combat training. They use a variety of weapons, ranging from pistols to heavy machineguns, yet are unable to block Rayne's attacks.
Waffen-SS troopers - members of the elite Waffen-SS, these troopers wear panzer-like leather jackets and use the same weapons as regular soldiers. However, they are faster, stronger and can block Rayne's melee attacks as well as use combat knives.
Waffen-SS low-ranking officers (unteroffiziers) - these NCO enemies differ from the regular SS troopers only in that they wear a grey coat. Otherwise, they are almost identical to regular Waffen-SS troopers.

Báthory Mengele - also known as the "Butcheress", was a Nazi scientist working for the Gegengeist Gruppe.

When Rayne watches from afar, she sees the Butcheress kicking victims into the pit of Daemites while laughing maniacally
P. Eckstein - is a Nazi Officer and a Major of the Gegengeist Gruppe. He worked closely with the Butcheress and experimented with the toxic gas, using the natives as test-subjects.

They use submachineguns, FG-42s and StG44s and can block Rayne's attacks with ease.
Hazmat troopers - To handle potentially hazardous materials, the G.G.G. outfitted several of their members with haz-mat suits. The air tight suits provided excellent protection against environmental hazards but were ineffective at stopping bullets or Rayne's blades. They possessed basic combat training.
Jetpack troopers - equipped with high power jetpacks and air filtering masks, the elite jetpack squads of G.G.G. were deployed during the assault on Castle Gaustadt as support units. Their main protection was their mobility, as the heavy protective coats, masks and steel helmets they wore were ineffective against weapons fire or cutting weapons.

Unknown officer - is mysterious Nazi officer of G.G.G. Nothing is known about who this person is.
Maraisreq - are large, arachnoid creatures that have over-run the city of Mortton, Louisiana. Their primary objective is to swallow people whole, then regurgitating the liquefied remains (somewhat similar to how an owl regurgitates).
Queen of the Underworld - is the "mother" of the Maraisreq and is more powerful than the generic ones, due to the sheer size of the creature. She can produce other Maraisreq out of a hole in its abdomen and attack at medium range.
Daemites - are parasitic/predatorial creatures that were awakened by the Nazis as they were searching for Beliar's skull. Despite not having any limbs and essentially being serpents, they are capable of standing up the entire length of their narrow bodies, making it difficult to hit them with bullets.

Beliar - is a powerful demon who once ruled Hell. He has a skeletal appearance, looking much like metal thorns with pieces of torn red flesh hanging from it.
Generic enemies: Primarily thugs. Both males and females make up the ranks of the minions (both human and vampire). They are lightly armored and go down with ease. Often armed with either melee weapons (crowbars, axes, swords, guitars, etc.) or guns (pistols, sub-machine guns, shotguns and occasionally tripod-mounted heavy machine guns).
Suicide Bombers: Used by the Kestrels and Slezz to do exactly what their name implies. They have a demolition timer strapped to their chests, which the detonate on getting close to Rayne. Aside from this, they are unarmed.
Ninja: A tricky opponent, the Ninja are the followers of Ephemera. They move very fast, and are able to block Rayne's harpoon attack using their electrified swords. They also attack from a distance by throwing Shuriken. Much like Ephemera, they appear to be dressed in BDSM-style leather.
Other Dhampir- were dhampir who wear black and red suits and the males use large scimitar-like swords. They also use dual guns. Another noticeable difference is that both males and females have heavy facial tattoos.
Foreman: These are large, turned vampires that carry heavy hammers and wear aprons. They are found almost exclusively in industrial areas, notably the large "Wetworks" facility that forms the Shroud-producing tower. What makes them extremely dangerous is that many of their attacks will knock Rayne to the ground, allowing easy follow-up attacks.
Brute: As their name suggests, they have a penchant for brute force and will attack other vampire minions if they get in their way. They have curved horns on their heads resembling those of a ram, which they use when charging head-first at Rayne.
Bio-Armor: Rayne only encounters a handful of these, similar in most respects to Brutes, except that the Bio-Armor are tougher. Although they have no heads, they have no problem finding and attacking their enemies. Xerx's bio-mech suit is a much larger version of the Bio-Armor.
Shadow Legion: A minor threat in most respects. Their speed and agility are daunting, but they are more susceptible to dismemberment than any other minion. The Shadow Legion wear masks with multiple lenses (possibly night vision goggles) and attack with ninja-like moves.
Kagan Elites: Heavily armored and armed with a sword in one hand and a machine gun in the other. They only appear close to the end of the game.
Unraveler: While in actuality a boss in its own right, the Unraveller is given no back story, and seems to be an indiscriminate killer, targeting minions as well as Rayne. It resembles a massive humanoid with long arms and legs, and attacks by spitting acid with enough force to throw enemies off their feet.
