The Scrapjack, or Scrapjack Rocketeer, is an enemy that appears in Serious Sam 3: BFE, Serious Sam 3 VR: BFE, Serious Sam's Bogus Detour,Serious Sam VR: The Last Hope and Serious Sam 4. It is the second boss of I Hate Running Backwards.

Overview[edit | edit source]

Scrapjacks are low-grade models of Mental's forces, created from sewn-together parts salvaged from KIA units of various other models. A Scrapjack has three selectable heads, which can exhibit various behaviors.

Variants[edit | edit source]

Three variants of Scrapjacks are known to exist. The common variety wields two rocket launchers, and a much larger version, known as Raahloom, wields a massive warhammer and a modified SBC Cannon. The Fattie Swallower is slightly larger than the regular Scrapjack, and fires large sawblades instead of cannonballs or rockets.

Occurrence[edit | edit source]

Scrapjacks are not usually as common as other enemies, and often appear in the later levels of whatever game they appear in. In combat, they usually serve a role of giving support to the main attacking force.

In Serious Sam 3, Scrapjacks first appear in the level Unearthing the Sun, with at least half a dozen of then appearing throughout the level. In the later levels, they're usually present one to few at a time, although there can be more in the final level. Over a dozen Scrapjacks appear in The Guardian of Time.

In Serious Sam's Bogus Detour, Scrapjacks are encountered much earlier compared to other games, appearing as soon as the second level, though they are more uncommon than before. Scrapjacks are often seen surrounded by groups of weaker enemies.

In Serious Sam VR: The Last Hope, the player may encounter several Scrapjacks at a time. They are encountered in the mid to late levels of the game.

Behavior and abilities[edit | edit source]

Scrapjacks exhibit different behaviors, and as a result can be dangerous if left unchecked.

Due to their large size and weight, Scrapjacks move very slow, often shaking the ground around them. A telltale sign that a Scrapjack is near is by listening to their heavy breathing and grunts, as well as the loud footsteps they make when moving. Their size and health allows them to endure multiple direct rocket hits, but can still be easily dispatched at a distance with concentrated fire from the M29 Infantry Assault Rifle, and even more easily eliminated by detonating a single C-4 charge that has been attached to their torso.

With three selectable heads to choose from, Scrapjacks show different behaviors, from bland attacking to berseking rage. Their firing patterns are very similar to the Zumb'ul; a Scrapjack will fire a rocket where the player currently is, and another where the Scrapjack predicts where the player's estimated direction is.  The Scrapjack also has a "berserk" mode when it has been damaged enough. In this phase, the Scrapjack will rapidly fire missiles in a much faster, longer succession just as accurately as regular attacking, just like Major Bio-mechanoids. Scrapjacks also have a strong melee attack if the player gets too close. Scrapjacks can also fire rockets if there is an obstacle between a player and Scrapjack, even if the obstacle is indestructible.

On Serious difficulty in the Serious Sam Fusion of Serious Sam 3, a Scrapjack has the chance to fire a volley of grenades. These grenades travel very far and explode a few seconds after landing on the ground. They can deal a lot of damage to an unsuspecting player, quickly draining them of their health and armor or kill them in just a few hits.

Unlike most enemies, the Scrapjack can only be executed with a melee attack if it becomes stunned under heavy fire from various weaponry. Not all weapons will stun the Scrapjack, however, though stronger ones such as the AS-24 Devastator and the XPML21 Rocket Launcher will always stun the Scrapjack under consistent fire. A special melee attack against the Scrapjack consists of the player ripping off the head of a Scrapjack, which is then followed by a kiss on the resulting trophy the player is left with.

Tactics[edit | edit source]

  • Scrapjacks are slow and the player cannot dodge their rockets easily. The XPML21 Rocket Launcher is one of the main ways to take Scrapjacks down, as they do not strafe as an attempt to avoid rockets, unlike Khnums. The AS-24 Devastator is an option when there are more enemies.
  • A skilled player can take down an entire volley of rockets fired by the Scrapjack with the assault rifle if they are accurate enough.
  • The XM214-A Minigun works good against a Scrapjack. If they don't have the minigun, the assault rifle also works, but it depletes ammunition quickly, and takes roughly 80 rounds to kill a Scrapjack (50-60 rounds in Serious Sam Fusion).
  • Lone Scrapjacks can be taken out with a single well-placed C-4 explosive or the Sirian Mutilator. Using the Mutilator is not always a good option, as the Scrapjack will pull the player closer to them when using it, leaving the player vulnerable to their melee attack or being swarmed by other enemies.
  • The grenades fired by the Scrapjack in Serious Sam Fusion on Serious difficulty are very dangerous and should be avoided by sidestepping in the opposide direction from which they are fired.
  • With other enemies, Scrapjacks are medium-priority targets. On Serious difficulty, they should be treated as high-priority targets. Their projectiles can be dodged with relative ease but it can prove quite difficult when there are many of them onscreen. At close range, their target priority is higher as it is hard to dodge their projectiles at close range.

Trivia[edit | edit source]

  • The Scrapjack looks and behaves much like the Mancubus from the Doom series. Also similarly to the Mancubus in Doom II, the Scrapjack's rockets can sometimes clip through walls, hitting the player even if the Scrapjack is on the other side of a solid barrier. This usually happens in areas where the Scrapjack is close to a wall.
  • Scrapjacks are one of the few enemies to tauntingly laugh when the player dies.
  • The Scrapjack's rocket launchers resemble the rocket launchers used by the Major Bio-mechanoid.
  • You cannot rip the Scrapjack's head off on Tourist difficulty, because their health is too low for them to be stunned.
  • While it is stated that Scrapjacks are built from sewn-together parts of other units, it is not explicitly specified which those enemy types are. The rocket launchers appear to be the same model as the ones used by the Major Bio-mechanoid, and as for the creature itself, it has a fleshy, human-like appearance, meaning that it must be made of human Cloned Soldiers and/or Sirian beheaded infantry. The Scrapjack's obesity and imposing size must be either a side effect of the manufacturing process, or completely on purpose (so as to be able to carry the massive rocket launchers that are too large to be wielded for a human-sized creature).
