The Minor Bio-mechanoid (Minor Mechanoid in Serious Sam: The Random Encounter) is a common enemy featured in many Serious Sam games. They are cyborgs armed with two pulse lasers that are attached to their sides. They are not as dangerous compared to their larger counterparts, which are armed with rocket launchers, though in large numbers they can still pose a threat.


The Minor Bio-mechanoid is a biological mechanism that was grown in Mental's bio-tanks. Its genome is programmed to give it artificially grown mechanical parts. Separately manufactured pulse lasers are attached to biologically designed side slots and are directly connected to its central nervous system. Like its larger counterpart, the Major Bio-mechanoid, the Minor has a large head that looks like a brain. Despite its appearance, though, it actually serves as a battery containment


In most of their appearances, Minor Bio-mechanoids are a light bluish color and have three horns protruding from their back. They also have a large exposed brain which covers most of their head, and mechanical legs with four bird-like feet. Despite the size of their brain, Minors are not programmed to be intelligent. In fact, they have the intellectual capacity of a cockroach. Minors also have mechanical legs with four bird-like feet; these legs contain servo rotors which are very loud when it moves, which can alert the player of its presence.

In Serious Sam 3: BFE, the Minor Bio-mechanoid's appearance has changed drastically compared to the previous games; their face is quite different, along with teeth and eyes with skin that looks like a brain. They also make different sounds.


Minor Bio-mechanoids are relatively common enemies. In Serious Sam: The First Encounter, Minors first appear in Sand Canyon, and in Serious Sam: The Second Encounter, they appear in Valley of the Jaguar, along with Major Bio-mechanoids. In Serious Sam 3, Minors are much less numerous. In the original version of the game, they first appear in The Silent Riddler, but can be seen in small groups in Under the Iron Cloud in the Serious Sam Fusion 2017 version of the game. They are more common in Serious Sam VR: The Last Hope and Serious Sam's Bogus Detour.


Compared to Major Bio-mechanoids, Minors are smaller, have less health and deal less damage. They are still as fast as Majors, though. When the Minor Bio-mechanoid spots a target, it will fire a rapid burst of blue lasers, then stop and do it again. As they have low health points, it only takes one rocket or explosive round to kill them. The Minor Bio-mechanoid's fire rate depends on the difficulty; on Tourist and Easy, it will fire its beams at a slow rate. On Normal and higher, it will fire them more quickly. No matter the difficulty, the lasers travel very fast and can quickly hit a non-moving target. Like the Major Bio-mechanoid, the Minor's main role is draw the player's attention away when faced with other enemies, or to provide support amongst groups of weaker enemies.

In Serious Sam: Double D and Serious Sam: Double D: XXL, the Minor's gun will fire a laser upwards, then move down while firing lasers until its gun is pointed close to the ground. However, there are gaps between each laser, making it possible to avoid its lasers. Minor Bio-mechanoid corpses can be jumped on and used as platforms, which is handy for reaching certain parts of a level.

In I Hate Running Backwards, Minors are the strongest ranged enemies in the game. They don't have as much health as they do in other games, though they are still dangerous if they are not eliminated quickly. The tier 2 variant switches its blue lasers for purple plasma balls. These travel at much faster speeds than the regular lasers, making them even more dangerous.



  • When facing Minor Bio-mechanoids, the player should always keep strafing. They cannot fire their lasers ahead of the player, making them harmless if they keep strafing in one direction.
  • On higher difficulty levels, Minors can be dangerous if left unchecked. Their rapid-fire lasers combined with the damage they do can drain the player's health if they aren't paying attention. Much like Beheaded Firecrackers, the player should attempt to kill them as soon as possible so that they can't drain the player's health while they're busy fighting off other enemies. On higher difficulties, they are mid-priority targets as there are enemies with harder-to-dodge attacks.

Serious Sam 1Edit

  • While the XPML21 Rocket Launcher is an ideal weapon against them, the Thompson submachine gun is a decent substitute if the player is low on rockets.
  • When forced to change direction, the best way to avoid getting hit is by jumping over the laser stream.
  • Minors can be easily defeated with the MK III Grenade Launcher or rocket launcher; it takes only one grenade or rocket round to kill them. Even groups of Minors of any size can easily be dispatched with these weapons, making them the perfect weapon against them. The RAPTOR Sniper Rifle is also useful at defeating them at longer ranges, as one zoomed shot is enough to kill one.
  • Groups of Minors can be taken out with rapid-fire weapons such as the Thompson or XL2 Lasergun. Rapid-fire weapons can quickly inflict damage on enemies, allowing the player to clear through groups of them with ease. The RAPTOR is also perfect for clearing out groups of Minors, as each shot from the sniper rifle is a one-hit kill. With some quick reflexes, the sniper rifle can wipe out a group of Minors even faster than the Thompson, XM214-A Minigun or lasergun can.

Serious Sam: Double DEdit

  • There is a noticeable gap between each laser fired by the Minor. Jump between these gaps in order to avoid the Minor's lasers.
  • Multiple rapid-fire weapons stacked together with a 12 Gauge Shotgun or an explosive weapon or two work very well against the Minor. The rapid-fire weapons and shotgun blasts can quickly inflict damage on a Minor, while explosive weapons can quickly kill the Minor if spammed by constantly hitting the fire key.
  • Multiple Minors should be dealt with by using a gunstack that has a mixture of powerful weapons, such as the shotgun and LM32 Rocket Launcher. Minors can easily be overwhelmed with powerful weapons, making it easy to cut down a group of them in no-time.
  • When paired with other enemies, the Minor is a high threat, but not because of the damage their lasers do. Its lasers can be quite annoying to dodge when trying to avoid other enemy's attacks, so the player should take it out as soon as they get a chance in order to give themselves more room to dodge other enemy projectiles.

Serious Sam: Next EncounterEdit

  • If the player constantly moves to the side, they will be able to dodge all of the Minor's lasers with ease.
  • Its lasers can be jumped over, which is very useful in emergencies.
  • The Double-Barrel Shotgun is very effective against the Minor Bio-mechanoid at close or medium range. One shot is usually needed to kill them.
  • Minors at a distance can be taken out with either the XPML4000 Rocket Launcher or the RAPTOR Sniper Rifle. The RAPTOR works better if they need to be taken out immediately.
  • Groups of Minors can be killed with the XM4000 Minigun, or, later in the game, the Sirian Power Gun. Both have a high rate of fire and can quickly do enough damage to cut down a group of Minors with ease.
  • Much like their Serious Sam 1 counterpart, they can become a nuisance if left unchecked. They should be taken out whenever the player gets a chance to do so.

Serious Sam 3: BFEEdit

  • The M29 Infantry Assault Rifle while using iron sights works great, as it has perfect accuracy while using iron sights and has a fast-enough rate of fire that it can tear up a Minor quickly. If no other significant threat is nearby, it can even be dealt with quickly using a few shots of either shotgun.
  • Against groups, the AS-24 Devastator, rocket launcher and lasergun are great weapons. The Devastator is a one-hit kill for a Minor, and can take out groups quickly without worrying about taking much damage or using up too much ammo.
  • The Sirian Mutilator is an ideal weapon, but only useful as a last resort and not when being swarmed by other enemies. The Minor can sometimes pull on the beam as well, putting the player at much greater risk of its lasers.
  • If the player has found the secret sniper rifle in The Last Riddler, they can use it to clear out most of the Minors that come at them. Be warned that ammo for the sniper rifle is rare, so plan accordingly when using it.
  • Just like the previous games, the rocket launcher is a great weapon against individuals or groups of Minors.
  • The SOP38 Pistol is also an effective weapon, but it takes more than an entire magazine to kill one.

Serious Sam's Bogus DetourEdit

  • As with Minors in previous games, the player can avoid the Minor's lasers by strafing or dashing.
  • Groups of Minor Bio-mechanoids can be taken down with the SBC Cannon, Devastator or Erasergun. Rapid-firing weapons are also effective against them.
  • Minors can also be taken down with the Flamethrower or The Shaft, but the Shaft can be a better choice, considering that it deals extra damage to them.
  • Shotguns can be also used against the Minor, provided that the player is close to it and quick enough to dodge its lasers.
  • When paired with other enemies, the Minor should be a medium-priority target. Its lasers can deal a high amount of damage, and they can make it difficult to avoid other enemy projectiles. Therefore, the player should kill the Minor whenever they have a chance.

Serious Sam VR: The Last HopeEdit

I Hate Running BackwardsEdit

  • As Minors fire their lasers quickly and their beams cannot be deflected or blocked, this makes them a formidable foe in numbers, especially if they have not been eliminated in time.
  • Due to their low health, a single blast from a shotgun is enough to kill one.

Behind the scenesEdit

  • In Test 1, an unused texture for the Minor Bio-mechanoid exists, which is grey. It can be seen in some old screenshots. The grey Minor Bio-mechanoid stayed until post-Test 2 time, as its sounds can be found in its files. Judging from the sounds, it could kick the player away.
  • The code for the Minor's lasers comes from the scrapped Cyborg enemy.


  • In Serious Sam 1, the Minor Bio-mechanoid has rocket launchers instead of its laser weapons in its NETRICSA description except in Serious Sam HD, Serious Sam VR and Serious Sam Classics: Revolution.
  • The Minor Bio-mechanoid is so destined to eliminate its target that it will fire its lasers at them regardless of friendly fire, and have killed more of their own comrades than EDF soldiers as a result.
