"You got a thick skin?"
Sam commenting on the Khnum's skin after attempting to damage it with a firearm.[src]

The Khnum is a large aggressive creature from the planet Arietis Lambda. They are very dangerous, and will stomp on the target if they get too close, or conjure fireballs to throw at the player from far distances.

They appear as a boss in Serious Sam 3: BFE, Serious Sam 3 VR: BFE, and The Legend of the Beast DLC.

Overview and appearanceEdit

The Khnum is a very large, bipedal creature, standing approximately forty five feet tall. Its grey skin and immense muscle mass make it both durable and powerful.

A Khnum's skin is extremely thick, with only rounds surpassing 30 mm caliber being able to penetrate it. Its head features red eyes, a gaping mouth showing razor teeth and two prominent horns similar to a goat, but not practical for use as a weapon. These horns are associated with the Egyptian god Khnum. They do not have feet, rather they have two large hooves that, while slow, allow it to walk as fast as Sam. They do have hands, each with three fingers and what appears to be an opposable thumb.

There is no apparent explanation with why they are working with Mental's forces, though it could be possible that they agreed to join his army, either in exchange for magical powers or other reasons.

NETRICSA descriptionEdit

"Khnums are a very powerful and aggressive race, originating from Arietis Lambda. On their home planet they are worshiped as gods by smaller creatures. They are not actually divine, but due to their thick skin and powerful regenerative capabilities, they can appear immortal. Due to their ram-like heads, this race is usually associated with the Egyptian god Khnum. Khnums are very powerful and dangerous opponents, relying on their immense physical strength and size to crush everything in their way and smash anyone who dares to oppose them."


Khnum Cairo

The first Khnum that appears in Cairo as a passing feature.

The Khnum first appears in Summer in Cairo as a passing feature, looking at the player but does not engage, as if disinterested. Later, it emerges after Sam activates the first Time-Lock generator, Horus. The first encounter with it takes place in Unearthing the Sun, in a relatively narrow corridor with pillars that can be destroyed and a crate full of C-4 explosives, which can help defeat it when no other explosive weapon may be available.

Later on in the campaign, Khnums appear most commonly alone or in pairs with groups of enemies. However, in the final level, several can appear at the same time. They usually appear with larger amount of weaker enemies. On easy difficulties, Khnums walk at a relatively slow pace. On harder difficulties, Khnums will walk/run faster at roughly the same speed as the player's walking pace.

Attacks and statsEdit

The Khnum has several attacks it may perform.

  • If the player gets too close, it may attempt a swipe, which deals high damage.
  • Also, it may use a hoof stomp attack which is faster, but does less damage.
  • Its ranged attack is a triple fireball that it conjures in its hand. It can toss it quickly for a quick attack, but this has less range and the fireballs are tightly grouped together. The Khnum usually performs this attack when it sees incoming projectiles from the player (such as rockets) and is strafing to dodge them.
  • It may also charge the fireballs, which is easily visible by the glow in its hand. This will make the fireballs travel great distances and also spread them out.

Although the fireballs have no target tracking of their own, the Khnum can throw them so that if the target is moving, it will hit the target if it continues its movement in the same direction. An easy counter for this is to change direction. The fireballs travel extremely fast and cause immense amounts of damage to Sam's health. Unlike missiles and fireballs in earlier Serious Sam games, a Khnum's fireballs cannot be destroyed by gunfire.


  • Due to its thick skin, bullets bounce harmlessly off a Khnum, regardless of where they're hit. Only explosives will damage a Khnum, with each explosive weapon sometimes being more appropriate depending on the situation. With C-4 equipped, a red C-4 target will appear on the Khnum's chest. Although effective, (requiring roughly three attached blocks of C-4) C-4 may not always be the best choice considering the distance required to successfully attach C-4. Khnums tend to run towards the player, bringing themselves, and the attached explosives closer to an unsafe distance. On the other hand, detonating an attached C-4 will always stun the Khnum, so consistently using C-4 can take it down without it attacking or advancing.
  • The rocket launcher is also another choice, but Khnums will actively dodge rockets shot at them, making hitting them difficult when not in close proximity. Khnums will also throw fireballs when dodging rockets, increasing the difficulty of successfully hitting one. This makes the rocket launcher one of the more challenging ways to engage Khnums, especially multiple groups. It is advised to fire rockets just as the Khnum starts charging, stop when the Khnum gets too close and then start firing again when it starts to use a ranged attack.
  • The AS-24 Devastator is a much better choice, doing roughly as much damage as the rocket launcher, but because the Devastator's projectiles travel faster, Khnums are unable to dodge each shot.
  • The SBC Cannon is a very effective weapon to take a Khnum down, needing only two fully charged hits. In addition, it causes them flinch after getting hit, preventing them from firing their fireballs. However, due to the rarity of cannonballs, players may opt in using other methods.
  • It is possible to decapitate a Khnum with the Sirian Mutilator, but only with at least two players using the Mutilator simultaneously. If a player attempts to decapitate a Khnum alone, then it will grab the beam and pull the player closer, which puts them in danger of a melee attack and usually disrupts the beam's charging process. Even if the player holds the charge indefinitely alone, the Khnum will not be decapitated.
  • However, using the Mutilator in single player against the Khnum can still be useful as it temporarily stuns it, stopping its charge and making the Khnum vulnerable to C-4.
  • With other enemies, Khnums are a medium-high-priority target. Their projectiles can be dodged at a distance but they deal a lot of damage and it can be hard to keep track of if other enemies are present.


The first Khnum encountered in the game serves as a boss. It is fought in Unearthing the Sun in an enclosed space filled with pillars, and has over twice as much health as a normal Khnum. The fight is fairly simple; there is a crate of (infinite) C-4 charges in the area, simply open it, run up the Khnum, throw the explosive charge on the creature's chest, then quickly detonate it. This will take a chunk off its life bar, and temporarily stun it. While it is stunned, throw another charge on it, detonate the charge, and repeat until it's dead. It should only take six or seven charges as long as you make sure to attach to the Khnum rather than detonate the pack near it. If you need to avoid the boss to gather more explosives or to just get to the ammo box in the first place, remember to use the pillars as cover to avoid its fireballs, and to sprint at all times, since the boss will be constantly trying to melee you.

Legend of the BeastEdit

The Khnum appears in the Legend of the Beast DLC as the final boss of the 3-level mini-campaign. It is found waiting for the player on its throne, in a reddish room. The room has a number of columns, which the Khnum can easily smash, but they will protect the player from an incoming fireball.

The room also has 6 switches and a metal platform in the middle, where a lightbeam shines. One of the switches is located above the Khnum's throne, and another one is on the opposite side of the wall, facing the one above the throne. 2 others are on the right and left upper wings of the room, and another group of 2 are on the right and left lower wings of the room. The ones on the lower wings of the room need to be activated in order for the one opposite of the throne to be activated. The one above the throne will not activate unless all others are active.

The Khnum has a tremendous health amount of 100,000, which makes it the second boss with the highest health in the Serious Sam series, only exceeded by the Mental Institution and Kwongo. Given that fact, your weapons will do no harm to it. Although, once all 6 switches are activated, if the Khnum is hit by the electric beam, it will take out 1/3 of its health if it stands in it for the full duration (the Khnum is stunned while hit by the beam). The Khnum will also punch the player if they get too close.

Unlike Khnums in Serious Sam 3, the Khnum from the Legend of the Beast is vulnerable to every weapon, aside from the Serious Bomb (which you cannot acquire normally in the mini-campaign anyway).

  • The Khnum originally appeared in a screenshot in a 2006 demonstration of Serious Engine 3, where it was smaller and had a slightly different face.
  • The Khnum, along with the Kleer Skeleton and Ugh-Zan IV, are the only enemies in Serious Sam 3: BFE that don't bleed (or splatter blood) when damaged or killed.
  • Its appearance is similar to the Baron of Hell from Doom and Hell Knight from Doom II, as is the fact that it is first encountered as a boss and has pale skin like the Hell Knight.
    • The way its legs bend mean it also slightly resembles the Cyberdemon, the second boss of Doom and final boss of Doom 3.
  • The Khnum is the only enemy in the Serious Sam franchise to be introduced in a new game and then retroactively added to an old one.
    • In its case, the Khnum was introduced in Serious Sam 3 in 2011, then added to Serious Sam HD: The Second Encounter, released in 2010, in the Legend of the Beast DLC, which itself was released in 2012.
