The Sirian Werebull is a dangerous enemy that appears in the Serious Sam series. They are aggressive creatures that will charge into and ram the target with their large horns.


The Sirian Werebull is a strange mixture of Sirian and cattle DNA, and looks and behaves very much like an ordinary bull.

The Werebull's only attacks are to charge and run up and gore the target with its horns. The Werebull's health allows it to endure several hits from most weapons before dying.


The Werebull's appearance varies from game to game:

  • In most of its appearances, the Werebull is a large bull-like creature with two long horns protruding from its head, with hands on its front legs and hooves on its hind legs.
  • In Serious Sam: Next Encounter, the Werebull has a much different design. It features an additional pair of horns and has red eyes and multiple rows of visible teeth. It is also a more dark greenish brown color than before.
  • In Serious Sam Advance, the Werebull has a more darker brown color than in Serious Sam 1.
  • In Serious Sam HD, Serious Sam VR and Serious Sam's Bogus Detour, the Werebull is pretty much the same as the Serious Sam 1 version, but has red eyes.
  • In Serious Sam 3: BFE, Serious Sam VR: The Last Hope and Serious Sam 3 VR: BFE, the Werebull looks a lot different; its horns are much longer, and the fingers on its front legs are larger. They also make different sounds.
  • In Serious Sam 4, the Werebull is larger and has longer horns. It now features a darker cream brown coloration with white patches on its head.


In Serious Sam: The First Encounter, Sirian Werebulls first appear in Sand Canyon near the end of the level. Throughout the game, they appear more frequently. In Serious Sam: The Second Encounter, Werebulls can seen as common enemies from the first level onwards.

In Serious Sam 3: BFE, the Werebull first appears near the end of Broken Wings as a boss. Later on, they only appear a handful of times throughout the campaign, where they are relatively common in The Silent Riddler and Born Again. They appear in the many dozens in The Guardian of Time.

In Serious Sam's Bogus Detour, Werebulls are rather uncommon enemies. The first one is encountered in Public Library No:1 and then appear one or two at a time later on in the game. They do not appear on the Moon base levels.

Behavior and skillsEdit

Behavior-wise, the Sirian Werebull behaves just like an ordinary bull. They are very aggressive and dangerous creatures, and will begin charging towards the target as soon as they see them. They will not stop chasing the victim until either the Werebull or the target has been killed, or if they lose sight of them. A Werebull will even charge through other enemies and ram them out of the way just to get to the player.

In-game, the Werebull has medium health and is one of the fastest enemies, making them a dangerous foe. Its two attacks consist of ramming the player, which causes the player to go flying into the air, or if the player is not fast enough, it will attempt to gore the player with its large horns, causing the same damage as a ram would.

The Werebull is capable of throwing the player over walls using its horns. Occasionally, the player may end up getting stuck in an inaccessible part of the map, which can sometimes result in having to reload to the last save point.

In The Second Encounter in The City of the Gods, there are several Werebulls armed with cannons that will fire a volley of fast cannonballs at the player. These cannonballs are very hard to dodge and deal massive damage, if not kill the player outright.


Serious Sam 1Edit

  • By far, the most important thing a player can do against Werebulls is to keep moving and strafing. Continuously moving prevents the Werebull from catching up to the player, and strafing prevents it from being able to hit the player.
  • One or two Werebulls can be taken out with the Double Barrel Coach Gun. However, this should only be done if there are weak or easy to avoid enemies near the Werebull, as it takes time to kill the Werebulls because of the long reload time between coach gun shots.
  • Charged up SBC Cannon cannonballs are very effective against groups of Werebulls. A charged up ball can tear through an entire group with ease (compared to the one or two a non-charged cannonball can kill).
  • If the player doesn't have a cannon and needs to kill a group of Werebulls, the XM214-A Minigun and the XL2 Lasergun can inflict a significant amount of damage on groups as well.
  • The XOP Flamethrower can also do major damage to a pack of Werebulls, but several seconds of continuous fire is needed to kill one.
  • At close range, explosive weapons are not recommended against Werebulls because there is a very real possibility of one getting close to the player while the explosive is in the air, causing the player to be harmed by the explosive's splash damage. At long range, it's a good option. Getting hit by a grenade makes a Werebull do a jump, though, so it's a bit harder to land a second shot.
  • A zoomed in RAPTOR Sniper Rifle shot will always kill a Werebull in one hit, which is useful for taking them out before they can even get close to the player.
  • When paired with other enemies, the Sirian Werebull is a high-priority target. Their charge attacks are powerful. And trying to dodge them while dealing other enemies is difficult.
  • In more confined areas, Werebulls are much more dangerous as they can turn around much faster. Aside from the charging attack, they can also stab the player with horns in these situations. The horn stab is not as damaging, but is much more difficult to avoid.
  • The more direct hits the player takes, the greater damage they receive. Jumping while dodging increases the chance of much smaller damage when getting hit, although the knockback is still retained.

Serious Sam 3: BFEEdit

  • Like its classic counterpart, the Sirian Werebull's charge can be avoided by strafing in one direction. Strafing at an angle makes it easier to avoid its charge, so try that whenever it's possible.
  • The coach gun works great against the Sirian Werebull; two shots with it can kill a Werebull if most of the pellets hit. Alternatively, the Sledgehammer can kill them with a few hits. A sideways attack hits them more reliably than the downwards attack.
  • The best chance to shoot it with the coach gun is when it's close while dodging. It may take some practice, but the player can easily shoot the Werebull with every pellet connecting.
  • Using the Sirian Mutilator against a Werebull will lasso onto it and eventually decapitate it, though this can be rather risky, as this usually requires the player to directly face the Werebull.
  • Multiple Werebulls should be taken out with heavy-duty weapons, such as the AS-24 Devastator, C-4 Demolition Charge or the SBC Cannon. One charge can wipe out a Werebull in one hit and greatly damage the other it if one of them walks over it when it blows up, or it's attached to the Werebull, while one cannonball can kill multiple Werebulls, even if it isn't charged up.
  • When paired with other enemies, the Sirian Werebull is a medium-high-priority threat. Its attacks are powerful, and trying to dodge it while dealing with other enemies is difficult. Killing it ASAP makes it easier for the player to avoid other enemies and their projectiles. However, some other targets firing hitscan projectiles should be dealt with before Werebulls.
  • Taking a direct hit by a Werebull charge can send the player to high places, such as a ledge or roof that would otherwise be impossible or very difficult to jump or climb onto.

Serious Sam AdvanceEdit

  • The Sirian Werebull's attack can be dodged by strafing to the left or right while it's charging. This will make the Werebull miss, giving the player a few seconds to attack it while it's trying to readjust itself to charge again.
  • The coach gun and Thompson submachine gun are effective against the Sirian Werebull. The Thompson can quickly do a good amount of damage on it per hit thanks to the amount of damage it does per bullet and its rate of fire. Its bullets can also briefly stun the Werebull, giving the player more of a change to dodge the Werebull. The coach gun is surprisingly not as effective as the Thompson because of its slow rate of fire and damage per second, but it works in a pinch.
  • The rocket launcher is effective against the Sirian Werebull, but it can be dangerous for the player if they are facing the Werebulls in a small arena. The Werebull can quickly close the distance between the player and itself while the rocket is in-air, which may cause it to explode close to the player, harming them.
  • Groups of Sirian Werebulls should be dealt with by using either the minigun or the rocket launcher. The Minigun's high rate of fire and lack of potential self-damage make it easy to kill Werebulls before they get too close, while the rocket launcher can kill multiple Werebulls with a few rockets, especially if they're close together.
  • When paired with other enemies, the Werebull is a high priority target. Trying to dodge them while dodging other enemy attacks can be difficult and cause the player a lot of grief. Eliminating them ASAP makes it much easier to dodge other enemy attacks.

Serious Sam's Bogus DetourEdit

  • Sirian Werebulls are extremely fast and dangerous. The player should dash or strafe sideways as soon as they hear or see one.
  • The cannon, lasergun, minigun and Devastator are effective weapons against the Werebull.
  • Avoid their charge attack whenever possible, as it deals a lot of damage.

Serious Sam: Next EncounterEdit

  • The Double-Barrel Shotgun is very effective against Werebulls. One shot can kill them at short range.
  • Groups of Werebulls can be taken out with the XM4000 Minigun and Sirian Power Gun. Their high rate of fire can take down Werebulls in no time. The double-barrel shotgun is also a good choice if the player is good at dodging them, as it is a one-hit kill and has a somewhat-low reload speed.
  • Werebulls should be a high-priority target because of how damaging they are and how it can be easy to lose track of them in a large firefight.

Behind the scenesEdit

  • An early Werebull model can be seen in the Serious Sam announcement movie. It had a less detailed skin and much longer horns.
  • They were two variations of the Werebull skins: the summer and the winter skin, as seen in SDK 1.07. Unfortunately, it may of been scrapped from the game.
  • Along with the Reeban Electro-Fish, the Sirian Werebull can be found in Serious Sam VR: The Last Hope game files, though it doesn't appear in any of the levels of the game.
