"Now that's a lot of bull."
Sam Stone[src]

The Sirian Werebull is a dangerous enemy that appears in the Serious Sam series. They are aggressive enemies 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 a bull, but has hands on its front legs and hooves on its hind legs.

Werebulls are very aggressive, and will begin charging towards Sam as soon as they see him. They will not stop chasing their target until they have been killed or if they lose sight of it.

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.


In Serious Sam 1 the Sirian Werebull appears a few times in the beginning of the game. Later, they appear more frequently.

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

Behavior and skillsEdit

The Sirian Werebull has medium health and is one of the fastest enemies in the games, making it 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 restart the game.


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 of Werebulls with ease (compared to the one or two a non-charged cannonball can kill).
  • If you don't have a cannon and needs to kill a group of Werebulls, the XM-214-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 you to high places, such as a ledge or roof that would otherwise be impossible or very difficult to jump or climb onto.

Serious Sam's Bogus DetourEdit

  • Sirian Werebulls are extremely fast and dangerous. Dash or strafe sideways as soon as you see it charging towards you.
  • The cannon, Laser Cannon, 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 has 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.
