"Ah, a Reptiloid. I could use a new handbag!"
Michelle Djabali[src]

The Common Aludran Reptiloid, or just Aludran Reptiloid, is a variant of Aludran Reptiloid and by far the most common type encountered in the series. They are ranged enemies that fire homing projectiles at the target.


The Common Aludran Reptiloid belongs to a species of four-handed reptilian creatures originating from the Aludran System, located in the constellation of Canis Major. During Mental's search for lifeforms that he could use in his army, he discovered the primitive race of the Reptiloids after their species was slowly dying off, and he offered them magical powers in exchange for them joining his army, to which they agreed.


Serious Sam 1[]

In Serious Sam: The First Encounter, Reptiloids start out from the Valley of the Kings, where they are rather uncommon enemies, but in the following levels, more and more of them appear, until they become common, although they don't appear in The Great Pyramid on solo play. There are lots of Common Reptiloids in Serious Sam: The Second Encounter as well, from the first level to the final level. They are more mobile in The First Encounter, compared to The Second Encounter, where they are usually stationary. Tiny Reptiloids appear in Sacred Yards and the secret "yard of strange-looking heads" in The City of the Gods.

Serious Sam 3: BFE[]

In Serious Sam 3: BFE, the Aludran Reptiloid only appears in Jewel of the Nile, where they are encountered on top of buildings or ledges, though sometimes they are mobile like they are in The First Encounter.

Serious Sam VR: The Last Hope[]

In Serious Sam VR: The Last Hope, the Reptiloid first appears in Court of Contemplation. Later on, they appear more common, often following the same spawning mechanics as they do in the previous games.

Serious Sam 4[]

This time around, the Reptiloid is a lot more common than in the previous games, occuring slightly more frequently than in Serious Sam: The Second Encounter. The first Reptiloid appears in Four Horsemen of the Apocalypse, and then on its own or in small groups later on. Several of them may be encountered at once in the later stages of the game, like in From Earth With Love.


Reptiloids, when they appear, play a similar role to Arachnoids and often spawn far away, such as on top of pillars, columns, roofs, and so on, in order to 'snipe' the target from a distance and to distract them. In some of their appearances, they appear more frequently on the ground, where they serve as low to medium-range assault or support units.

Behavior and skills[]

Like other species of Reptiloids, the Common Reptiloid is skilled in casting the magical spells that Mental granted them. The Reptiloid is covered in tough scales that can prove useful in combat, as it grants them decent protection from bullet-firing weapons. Despite these advantages, though, they can still be easily dispatched from a distance with a powerful sniper rifle or weapons that fire explosive projectiles.

Behavior-wise, the Reptiloid does not charge towards the player like most enemies, instead preferring to keep its distance and often remaining stationary. Upon spotting the target, the Reptiloid will cast a magical green energy ball that will track the target. This homing ball will try to hit the target, and if it misses, it will turn around and try again. This projectile only lasts for a certain amount of time before it explodes on its own. The projectiles cast by the Reptiloid can be shot down by firearms, but will not be destroyed upon impacting with a surface or wall, unlike the lava balls tossed by the Fiendian Reptiloid Demon and Highlander Aludran Reptiloid in Serious Sam: The Second Encounter. The projectiles only last for a certain period of time before exploding in mid-air.

From Serious Sam HD onwards, should the target get too close to a Reptiloid, it willl deliver a powerful melee attack that consists of a punch or a stomp. Its melee attacks are far more powerful than its fireballs, so the player should avoid getting too close to one for that matter.

In Serious Sam VR: The Last Hope, the Reptiloid behaves the same as it does in the other games, but it rapidly fires a burst of projectiles in succession in a similar manner to the Highlander, making them more dangerous than before. The Reptiloid is also stronger than in other games, though the ability for dual-wielding weapons still makes it easy to kill it with strong weapons.

In Serious Sam 4, the Reptiloid is a lot more mobile than before, and will try to get closer to the player rather than keep its distance. If it has taken considerable damage, it will enter a 'berserk' state and charge towards the player, firing multiple fireballs at once. Like other enemies, the Reptiloid will become stunned briefly if it comes under rapid heavy fire. It will also take extra damage if it is shot in the head with any projectile-firing weapon.



  • The XL2 Lasergun and XM214-A Minigun are good weapons against a group of Reptiloids, as not only do these weapons kill them relatively quickly but also help to shoot down their fireballs as well.
  • The XPML21 Rocket Launcher is also a good weapon for destroying Reptiloids from close-to-medium range. It's not very reliable for further distances, as the rocket may impact with the projectile instead. This has a smaller chance of happening at close range.
  • The MK III Grenade Launcher is a strong weapon to use against the Reptiloid; three or so grenades will kill it, though this depends on accuracy and the player's distance from the Reptiloid. As it requires precision to aim far with grenades, it is recommended to fire grenades at them from medium to close range.
  • With other enemies, Reptiloids should be high-priority targets, especially on higher difficulties, as their projectiles can become dangerous if left unchecked. This is especially the case if rapid-fire weapons have not been obtained yet.
  • One of the best anti-Reptiloid weapons is the RAPTOR Sniper Rifle. Three shots (two shots in the HD and VR remakes) are enough to bring them down.

Serious Sam 1[]

  • The SBC Cannon can be used as a last resort against this enemy, but it is not recommended as cannonballs will often explode on impact with a Reptiloid, especially in Serious Sam: The Second Encounter, where the cannonballs always explode upon touching a Reptiloid regardless of the charge.
  • The sniper rifle can dispatch a few Reptiloids easily from a safe distance, as long as there aren't any other enemies around to distract the player.

Serious Sam Advance[]

  • The Reptiloid's projectiles can be avoided by strafing either left or right in one direction.
  • The Time Strike is very effective against Aludran Reptiloids, as it will always hit them, and it takes only two strikes from it to kill them.
  • The rocket launcher in this game is not very effective against the Reptiloid because rockets will explode if they hit a projectile fired by the Reptiloid. Since the Reptiloid has a fairly fast rate of fire, this means most of the rockets fired at a Reptiloid will just explode before they hit it.
  • Multiple Reptiloids should be dealt with by using rapid-fire weapons, such as the Thompson submachine gun or the minigun. These rapid-fire weapons are powerful enough to quickly kill each one if the player focuses on them one at a time. The minigun is better for dealing with Reptiloid groups than the Thompson because of its higher rate of fire, but the Thompson works just as well in a pinch.
  • When paired with other enemies, the Reptiloid is a high-priority threat. Its projectiles are powerful, and it is placed so that it can easily hit the player while they are distracted by other enemies. The player should eliminate it as soon as they get a chance to target it.

Serious Sam: Next Encounter[]

  • The Reptiloid isn't as dangerous as it first looks. Its green orbs are easy to dodge, and aren't as damaging as its larger counterpart, the Highlander Aludran Reptiloid.
  • Zoomed-in sniper rifle shots are very effective against it, as one shot will kill a Common Reptiloid.
  • If the player has to fight a Reptiloid close up, the Double-Barrel Shotgun works very well. A point-blank shot is about as powerful as a rocket and lacks the rocket's splash damage. It takes about three shots to down a Reptiloid.
  • Long-range Reptiloids can be taken down with a barrage of rockets if the player lacks a sniper rifle. About four should be enough to kill it.

Serious Sam 3: BFE[]

  • The sniper rifle is an excellent weapon to use against a Reptiloid, as it has a fairly high rate of fire and does a lot of damage against it per hit. Three or so shots should be enough to kill it.
  • Reptiloids are slow and even usually stationary when located in elevated places. Thus a rocket launcher is a viable alternative for killing them. Note that the Reptiloid's projectiles can destroy rockets so more than 3 may be needed.
  • The M29 Infantry Assault Rifle and lasergun also work well against the Reptiloid. They not only can do a good amount of damage to a Reptiloid quickly, they can also destroy the Reptiloid's projectiles right or soon after they're tossed by a Reptiloid.
  • The A-24 Devastator and is an ideal weapon against the Reptiloid. Its projectiles are fired fast enough to destroy the Reptiloid's projectiles and kill it before the fireballs reach the player.
  • A Reptiloid's projectiles can be dodged by simply strafing left or right.
  • If a Reptiloid projectile is dodged, it will often try and hit the player again. It's best to turn around and destroy it as soon as it's avoided, or else the player may be in for a nasty surprise a few seconds later.
  • When paired with other enemies, the Reptiloid should be one of the first enemies killed. It's easy to lose track of its projectiles in a heated firefight, which can lead to deadly consequences later on. It's best to eliminate a Reptiloid as soon as possible so that the player no longer needs to keep track of the green balls it's shooting while dealing with other matters.
  • When a situation requires the use of rapid-fire weapons, Reptiloids should be medium-priority targets as rapid fire weapons can shoot down projectiles with ease.

Serious Sam 4 / Serious Sam: Siberian Mayhem[]

  • The Reptiloid is easier to kill in these installments thanks to the dual-wielding system and the headshot mechanic.
  • Fire at the Reptiloid's head when possible; it will take more damage this way and make it easier to finish the Reptiloid off. The Devastator, TCC2 "Perun" Crossbow, and sniper rifle work well for this purpose.
  • At close range, dual-wielded Double Barrel Coach Guns are very effective against the Reptiloid.
  • The Devastator, grenade launcher, and rocket launcher are very useful for dispatching close to medium-range Reptiloids.
  • Despite its weak damage output, it is possible for the player to kill a Reptiloid with the SOP38 Pistol (especially if they want to earn the Pow Pow! achievement), but it takes a considerable number of shots to kill one with it and leaves the player vulnerable to its fireballs. It is best used to finish off the Reptiloid unless the player dual-wields them and shoots it in the head with them.
  • The sniper rifle is an excellent weapon against them; one shot to the head will kill it.
  • Strong weapons, such as the cannon, XPMR "Burner" Raygun, and FRPCL, can be used to safely dispatch Reptiloids from medium to far range.
  • If riding another enemy (by unlocking the respective skill in the S.A.M. system), especially a slow-moving one like a Major Bio-mechanoid or Khnum, Reptiloids should be dealt with immediately to avoid excessive damage to the monster the player is riding. Khnums can quickly kill Reptiloids with just three fireballs, although some Reptiloids will spawn on top of buildings that can easily block the Khnum's fireballs. For this reason, the player should fire their own weapons while on top of the enemy they have mounted to destroy the Reptiloid projectiles before resuming dealing with other enemies using the mounted enemy's attacks.

Behind the scenes[]

  • Early Serious Sam 4 concept sketches depict a Reptiloid with different colored skin and wearing a skull on its head. It can also be seen conjuring blue fireballs as opposed to the usual green ones.


  • Although the Reptiloid bleeds green blood in Serious Sam 1, when killed, it may leave behind a puddle of red blood. From Serious Sam HD onwards, it correctly bleeds red blood like with all other Reptiloid variants.
  • The fireball tossed by the Reptiloid in Serious Sam 3 uses the same model as the one in Serious Sam HD.
  • The Reptiloid is called 'Beast' in Serious Sam's game files.
