Ever since Fortnite introduced the weapon crafting system, players have been clamoring to use old weapons again. In Chapter 2: Season 7, the crafting system expanded, allowing anyone to make alien weaponry.

Making extraterrestrial weapons rely on one main component: Alien Nanites. This new crafting material can not only let you make powerful weapons but also reduces gravity mid-match. Keep on reading to find out more about this unusual material.
Fortnite Alien Nanites Locations
Things rarely fall out of this battle royale’s sky except for Supply Drops and enemy players. The weapon crafting system expansion changed that, though, with the introduction of Alien Nanites.
You’ll need to pick up Alien Nanites before you can make alien guns or use their inherent abilities. To help you with this, we’ll show you where to find these exotic items.
The best place to find Alien Nanites is within the Mothership. The chests within the Mothership’s Vaults may contain Alien Nanites, but you need to complete The Experiment first. If you’re cautious about searching the Mothership, there are alternate ways to get a hold of Alien Nanites.
Invaded Locations are hotspots for Alien Nanites. They may be in three of these areas on the island during any given game:
- Craggy Cliffs
- Retail Row
- Lazy Lake
- Slurpy Swamp
- Misty Meadows
- Holly Hatchery
- Boney Burbs
- Believer Beach
- Steamy Stacks
- Dirty Docks
- Pleasant Park
Three Trespassers flying in Saucers will appear on the map in each game. You can buy Alien Nanites from them.
Alternatively, Alien Nanites are also floor loot. Their Common rarity lets them appear more often, but it’s pure luck if you find one near your drop location.
Some report that they’re more common near alien locations, such as the top of Abductors. However, any floor loot spot has a possibility of spawning Alien Nanites, so we recommend you check out all the floor loot nearby.
How to Get Alien Nanites in Fortnite
One of the most reliable ways to get Alien Nanites is by boarding the Mothership and participating in the Experiment. The second is to trade with Trespassers. You can buy an Alien Nanite for 150 Bars.
The Experiment
To participate in the Experiment, players must approach an Abductor and let it capture them. Next, you’ll find yourself on the Mothership, in an area comprised of pieces of the island. Parts of Slurpy Swamp are currently part of the Experiment.
Each player has 90 seconds to use their Alien Knockgun Launcher to prevent others from obtaining Vault Orbs. They can also pick up Time Orbs to increase their time by five seconds per Orb. The more Vault Orbs they gather; the better each player’s rewards are.
Due to the Alien Nanites’ Common rarity, you can expect to get a few most of the time.
Buying Alien Nanites From Trespassers
Chapter 2: Season 7 saw the introduction of Trespassers. These AI units are low-ranking soldiers working for “The Last Reality.” Trespassers can pilot Saucers and patrol locations they currently control.
These Invaded Locations have purple names and occasionally have distorted text.
When you approach a Trespasser, they may assume the form of any island character, thanks to their shapeshifting powers. However, they usually don’t attack if you only want to buy their wares.
You can buy more than one Alien Nanite if you have the funds. Each one costs 150 Bars, which is relatively inexpensive compared to the Kymera Ray Guns and Prop-ifiers, which cost 600 Bars each.
What Do the Alien Nanites Do?
When you get Alien Nanites, they take up a slot in your inventory. Each space can hold a stack of two Nanites. If you have an Alien Nanite, there are two ways to use them: throw it like a grenade or use it as a Crafting material.

The exception is when it becomes a quest requirement. One of Chapter 2: Season 7’s quests require that you deploy an Alien Nanite for completion.
Low-Gravity Grenade Function
Equipping an Alien Nanite allows you to throw it like a grenade. Once it lands on a surface, you’ll see a purple rectangular field. It’s relatively large, and you’ll experience low gravity within the area.

This low-gravity field is like the one found in Holly Hatchery. It only lasts for 30 seconds, so you’ll have to make the most out of it. During this short time, you can jump higher and land without fall damage.
There are two ways of using this low-gravity field. You can use it as a quick escape method or reach high places without consuming Materials.
Using an Alien Nanite as an escape route may be reminiscent of the Port-a-Fort and Shockwave Grenades. The former had bounce pads to negate fall damage, and the latter could effectively prevent fatal falls.
When falling from a high place, you can throw the Alien Nanite on the ground to prevent falling damage. Once you land, you can still use the low-gravity field to your advantage.
If you want to get to high places without wasting precious Materials, throwing one down helps immensely. You can jump to areas you never could before, thanks to the increased jump height and no risk of falling to death – for 30 seconds duration of the Nanite.
Craft Weapons With Alien Nanites
Those who thought Alien Nanites were useless likely didn’t take a peek at their Crafting menu. These glowing cubes are more than just grenades. They are highly coveted Crafting Materials, too.
The rarity of your original weapon determines the alien weapon’s rarity as well. For example, a Rare Assault Rifle becomes a Rare Pulse Rifle. You can only use Rare, Epic, or Legendary weapons when Crafting.

All alien weapons only require one Alien Nanite as a Crafting Material. You can make more weapons if you have extra Nanites, though. Using them as grenades is also an option.
Here’s a list of every weapon you can craft using Alien Nanites:
Kymera Ray Gun
The Kymera Ray Gun requires a Submachine Gun, Suppressed Submachine Gun, or Rapid Fire SMG. Uniquely, this gun has infinite ammo balanced with a cooldown period. Kymera Ray Guns can be Rare, Epic, and Legendary.

Pulse Rifle
Pulse Rifles come from combining Assault Rifles or Heavy Assault Rifles with one Alien Nanite. It boasts excellent hip fire and increased damage when aiming. These rifles have the same three rarities as Kymera Ray Guns as well.

Rail Gun
Any Rare and above Bolt-Action Sniper Rifle you come across can be used to craft a Rail Gun. Rail Guns can fire through buildings and specific surfaces. It’s slow but highly destructive.

Plasma Cannon
Only Legendary Pistols or Hand Cannons are eligible Crafting components for Plasma Cannons. Plasma Cannons can only fire five times and cannot be reloaded, making their use highly challenging. The plasma balls it fires can go through buildings, too.

Guns Out of This World
Finding Alien Nanites can be a challenge since they don’t appear very often. However, if you manage to get your hands on one, crafting alien weapons can give you an edge in battle. Their use as grenades for preventing fall damage or climbing is also helpful in a pinch.
