No Man’s Sky Larva Cannon is the new living Multi-Tool added with Forsaken 7.10 on 28 October 2026. You obtain it from a Forsaken trader at a deep-space outpost by paying preserved grubs. The Larva Tank helmet and Mind Harvester title are separate rewards tied to gathering haunting mementos.
The cannon is made from a creepy larval shell, while the helmet holds a wriggling creature inside a tank. They’re two different rewards with different requirements. Here’s how to get each one without confusing preserved grubs with haunting mementos.
How to unlock the No Man’s Sky Larva Cannon
Install the Forsaken update, visit a space outpost and summon a Forsaken trader. These new merchants have the organic corvette parts and the living Multi-Tool introduced in version 7.10. You’ll need to check their stock for the cannon.
The No Man’s Sky Larva Cannon is sold in exchange for preserved grubs. Hello Games confirms the currency, but doesn’t state a fixed number in its patch notes. Check the trader’s displayed cost before gathering a specific quantity or spending anything.
Where to get preserved grubs for the No Man’s Sky Larva Cannon
The official Forsaken notes name preserved grubs as the purchase currency, but don’t give a guaranteed grub location or farming method. That means we can confirm what you need to pay, but not a reliable route or drop rate from the developer’s announcement alone.
If you’ve already found some grubs, compare your inventory with the vendor’s price. Don’t mistake a haunting memento for the required grub: Hello Games lists mementos for corvette modules and preserved grubs for the Larva Cannon. The two items aren’t interchangeable in the stated shop requirements.
Is the No Man’s Sky Larva Cannon the same as the Larva Tank helmet?
No. The Larva Cannon is a Multi-Tool that you can use as equipment. The Larva Tank is an exosuit appearance showing a larva inside a glass container. Buying the weapon isn’t listed as a way to unlock the helmet.
Hello Games describes the No Man’s Sky Larva Cannon as a living Multi-Tool made from an unknown larval exoskeleton. Its appearance is confirmed, but the patch notes don’t give a full damage or technology-stat comparison with other Multi-Tools. There’s no reason to assume it’s automatically the strongest option.
How to earn the Larva Tank helmet and Mind Harvester title
Both cosmetics are connected to collecting haunting mementos. The new items can be found at infested outposts, deep-space hulks, derelict freighters and planetary digsites. Hello Games says dedicated collectors can earn the Larva Tank helmet and the Mind Harvester title.
Explore those locations and gather the new salvage, but don’t follow an unverified claim that a particular number of pickups automatically awards both cosmetics. The official notes don’t give exact milestones or confirm that the helmet and title unlock together.
No Man’s Sky Larva Cannon, Larva Tank and title: reward comparison
| Forsaken reward | How it is obtained |
|---|---|
| Larva Cannon Multi-Tool | Buy from a Forsaken trader with preserved grubs |
| Larva Tank helmet | Earn through haunting-memento collection |
| Mind Harvester title | Earn through haunting-memento collection |
The distinction is simple: preserved grubs buy the cannon, while the memento collection activity is linked to the cosmetic rewards. Forsaken traders also accept mementos for new corvette cockpits, interiors and hull parts. The table above separates the three rewards so you can see which activity to pursue.
The memento-hunting side carries risk: handling the unsettling samples for too long attracts hostile boundary horrors. You can start collecting at an infested outpost or find salvage in a deep-space hulk or freighter. Our memento locations guide covers that part of the update.
Can you get the No Man’s Sky Larva Cannon for free?
The update itself is free for existing No Man’s Sky owners. There is no separate Larva Cannon DLC to buy, but the weapon still costs in-game preserved grubs at a Forsaken trader. Hello Games hasn’t announced a paid shortcut or redemption code for it.
For the No Man’s Sky Larva Cannon, start at a space outpost and check the trader’s preserved-grub price. For the helmet and title, start collecting haunting mementos instead. Our memento locations guide covers where to find them, while our full 7.10 update guide covers the other additions.
