Fortnite Save the World Constructor Class Guide for Beginners

A Constructor is the only class in Fortnite: Save the World that is capable of doing defense mission single-handedly. They are also the most efficient at enabling AFK missions such as Endurance or Retrieve the Data, and are a must-have for any stationary-objective mission with the incredible B.A.S.E. ability, that enhances your structures to provide better protection, self-heal, and even deal damage to enemies.

There are plenty of Constructors to choose from, and it can certainly be hard to find the right loadout with there being a Commander slot and six other slots for you to fill. This Fortnite Constructor Class Guide will help you understand what Constructors work best for which situation, along with a few top-tier builds in Save the World.

Understanding the Constructor Class

Constructors can be broadly categorized into three types:

  1. Build-based
  2. Melee-based
  3. Ability-based

Melee-based Constructors are ones such as Tank Penny or Guardian Bull, that utilize hardware weapons such as clubs and hammers to deal damage. Ability-based Constructors are a wider variety that involve Constructors such as Airheart that specialize in improving the damage or efficiency of a particular Ability.

While these two are pretty fun to use, they are nowhere near the build-based constructors, that are the real meta of Fortnite: Save the World. These are the Constructors that enhance your builds by boosts such as increased wall health, or a greater B.A.S.E. range. These Constructors are one of the best Heroes in Save the World and are a must-have in every squad for defense-based missions. In fact, if I join a squad and don’t see a Constructor, I bring my own B.A.S.E. Kyle Loadout!

Meta Constructors in Fortnite: Save the World

Here are the Constructors and the Perk you will require for the best Loadouts in Fortnite:

  1. B.A.S.E. Kyle: Increases building health by 28% (84% if Commander)
  2. Supercharged Traps: Increases damage dealt by traps by 8.5% for each Constructor in Loadout.
  3. Mega B.A.S.E. Kyle: Increases BASE connectivity range by 1 (3 if Commander)
  4. Machinist Harper: Increases Trap Durability by 17.5% (52.5% if Commander)
  5. Power B.A.S.E. Knox: Structures affected by B.A.S.E. are healed for 4% of Max Health (11% if Commander) every 10 seconds.
  6. Heavy B.A.S.E. Kyle: Eliminating enemies standing on structures affected by B.A.S.E. charges B.A.S.E. After 30 charges B.A.S.E. emits an explosion which knocks back enemies and deals 39 base Energy Damage in a 3 tile Radius (89 in a 5 tile Radius if Commander).
  7. Electro-Pulse Penny: Enemies that melee attack structures affected by B.A.S.E take 15 base damage (44 base damage if Commander).
  8. Ice King: Enemies standing on structures affected by B.A.S.E. are Snared by 15%. (If Commander- Enemies standing on structures affected by B.A.S.E. are Snared by 15%. Enemies that damage a structure affected by B.A.S.E. are Frozen for 4 seconds. Each enemy can be Frozen once every 15 seconds.)

The three best Commander slot Constructors in Fortnite are:

  • Mega B.A.S.E. Kyle – for Storm Shields and four Atlas defenses
  • B.A.S.E. Kyle – for all other missions
  • Power B.A.S.E. Knox – same as B.A.S.E. Kyle

These are the ones that provide the best enhancements for your structures.

Best Constructor Loadouts in Fortnite

Here are the best Fortnite Constructor Loadouts:

Defense Missions

This is the best build for all defense missions except Storm Shields and Fight Category 4 Storm:

  • B.A.S.E. Kyle – Commander
  • Supercharged Traps – Perk
  • Mega B.A.S.E. Kyle
  • Machinist Harper
  • Power B.A.S.E. Knox
  • Heavy B.A.S.E. Kyle/Electro-Pulse Penny/Ice King (pick any two)

You can swap B.A.S.E. Kyle and Power B.A.S.E. Knox if you want, depending on who you prefer as your Commander.

Storm Shields and Fight Category 4 Storm

This is the best build for Storm Shields and Fight Category 4 Storm:

  • Mega B.A.S.E. Kyle – Commander
  • Supercharged Traps – Perk
  • B.A.S.E. Kyle
  • Machinist Harper
  • Power B.A.S.E. Knox
  • Heavy B.A.S.E. Kyle/Electro-Pulse Penny/Ice King (pick any two)

The major difference between the two builds is the B.A.S.E. range. The second loadout covers a greater range while sacrificing on some of the structure strength, while the first loadout covers a smaller range while packing on a lot of structure strength. In case of the second loadout, the build strength is worth sacrificing for the greater range, as it is more important to protect all four Atlases than just one.

Ice King is another candidate for a Commander, but it is certainly not the best idea to lose the valuable structure strength provided by B.A.S.E. Kyle when slotted in the Commander Slot. Some people also prefer using the Recycling perk, but I highly recommend Supercharged Traps instead, since Recycling generates a pretty low amount of building material. The only place where you’d actually want Recycling is on AFK/Jail Builds, where trap damage doesn’t make any difference.

How to make the most of your Constructor

Here are some important tips that will help you make the most of this powerful and versatile Class:

  • Level up and properly perk up your traps: You will be using them more often than not. Crit builds work the best for most traps!
  • Send a lot of Expeditions: This will help you stock up on the resources needed for building and trapping. Expeditions are free, and only require you to temporarily slot in some of your Heroes.
  • Master the best builds: Every situation demands a different build. Try to learn the best builds for each situation, such as minimal Jail Builds, and efficient tunneling.
  • Invest in Ability Strength: Ability Strength will help you gain the best buffs a Constructor can ask for.
  • Block Smashers: One of Constructors’ best Abilities is Bull Rush. When timed properly, it can easily stop a charging Smasher and protect your fort from crashing down.
  • Position Anti-air Traps properly: These will make a big difference in protecting your fort from Lobbers and Flingers, which are often the reason why high-level missions fail. Protecting your fort from the top matters!


Constructors are a versatile and powerful class, and having a good one on your squad can make all the difference. Constructors can not only make missions easier by enabling the much-needed fort safety, but also make some of the annoying in-game modifiers much easy to deal with. We hope our Fortnite Constructor Guide helped you understand the Class better. Good luck, Commander!
