Key Highlights:
- Kelvin is your first companion in Sons of the Forest and can gather resources, finish structures, maintain bases and perform other non-combat jobs.
- The Maintain Base command lets Kelvin fill storage, complete unfinished structures, repair damage and sharpen defensive walls.
- Enemies can incapacitate Kelvin, but the player can revive him. If Kelvin is fully killed, normal gameplay does not provide a resurrection option.
Quick Links:
Kelvin is the first AI companion available in Sons of the Forest. His main role is labour rather than combat.
He can gather resources, finish construction, maintain a base and collect food while you explore or handle jobs that require direct player control.
Kelvin cannot use weapons or fight enemies, but that limitation is exactly why I would use him as a permanent base worker rather than treating him like a conventional follower.
Where to Find and Recruit Kelvin
Kelvin is found beside the helicopter crash site at the beginning of the game.
Approach him after regaining control and interact with him to help him to his feet. Kelvin suffered a serious head injury during the crash, leaving him unable to hear or speak.
Commands are therefore given through a written notepad rather than dialogue.
Once Kelvin is active, his position is marked by a blue K on the GPS Tracker, making it easier to locate him if he falls behind or wanders away from your base.
How Kelvin Commands Work
Kelvin follows a predefined set of commands selected through the notepad.
| Command | What Kelvin Does |
|---|---|
| Follow Me | Follows the player across the surface |
| Get | Collects available Berries, Fish, Sticks, Rocks, Stones, Arrows, Radios or Logs |
| Build | Creates basic structures or helps finish an existing structure |
| Stay | Remains at the current location, a shelter or a hidden position |
| Take a Break | Stops working and rests |
| Clear | Clears an area within a 5, 10 or 20 metre radius |
| Maintain Base | Performs several base-maintenance jobs automatically |
| Take Clothing | Lets you change Kelvin’s outfit |
The options available after Get depend on the selected resource and nearby storage. Kelvin can drop gathered items, bring some resources directly to you or place suitable materials into holders.
The full release renamed the old Take Item command to Take Clothing, so older Kelvin guides may still use the previous menu name.
Best Ways to Use Kelvin
Kelvin is most useful when he handles repetitive jobs that would otherwise keep you close to camp.
Gathering Logs and Building
Log gathering is one of Kelvin’s strongest jobs.
He can cut trees, carry two Logs at once and deliver them to suitable storage. If you already have a construction outline placed, the Finish Structure command lets Kelvin add the required materials for you.
Kelvin now continues working through every compatible unfinished structure he can reach instead of stopping after completing one.
That makes him particularly effective when you place several blueprint structures before assigning him to construction.
The newer drawn Defensive Wall system also works with Kelvin. You can lay out the wall route and leave him to complete the placed structure.
The notorious launch-period problem where Kelvin could chop down the tree supporting your treehouse has also been addressed. Current versions make him choose another tree when a player structure is attached to his original target.
Using Maintain Base
Maintain Base is Kelvin’s most useful general-purpose command once you have an established settlement.
When Kelvin maintains a base, he can:
- fill available storage holders
- complete unfinished structures
- repair damaged structures
- sharpen placed Defensive Walls
This is more useful than repeatedly giving him individual gathering orders when your base already contains storage, unfinished construction and defences that need attention.
I would use Maintain Base when staying near a permanent settlement and switch to specific Get commands when one particular resource is running low.
Getting Fish
Kelvin can collect Fish directly from suitable water sources without a Fish Trap or Crafted Spear.
The Get Fish command is still one of the easiest ways to secure food early, particularly before you have a larger food-production setup. Our Sons of the Forest fishing guide covers the other fishing methods separately.
Kelvin does not fish forever, however. His fishing order ends after a period of time, so you must issue another command if you want him to continue.
That behaviour replaced the much stronger launch version where Kelvin could generate Fish indefinitely from a single instruction.
Gathering During Winter
Kelvin remains useful when snow changes what the player can collect directly.
During winter, loose Rocks and Small Rocks become unavailable for the player to pick up beneath the snow. Kelvin can still complete rock-gathering tasks.
That makes him particularly useful for keeping construction materials moving during the winter season instead of waiting for the snow to disappear.
Kelvin Behaviour and Limitations
Kelvin manages his own basic survival needs.
He eats, drinks, sleeps and rests without requiring you to maintain separate hunger or hydration resources for him. Kelvin may stop between jobs to recover before returning to work.
The Take a Break command gives him an immediate rest period when you want him to stop working or remain out of the way.
Kelvin also reacts to nearby enemies. He can point towards a detected threat and will retreat rather than entering combat.
You cannot give Kelvin a Pistol, Shotgun or another weapon. For armed companion support, Virginia fills a different role because she can use firearms once befriended.
Kelvin also does not follow you through normal cave exploration. He remains outside while you enter and can resume following after you return to the surface.
His surface navigation has improved considerably since launch. Kelvin can swim, follow the player through water and pull himself out at reachable edges.
Can Kelvin Die and Be Revived?
Kelvin can be incapacitated and revived, but being downed is different from being permanently killed.
When Kelvin takes enough damage from enemies, he enters a downed state. Approach him and use the revive interaction to return him to normal activity.
Enemy attacks are generally designed to incapacitate Kelvin rather than deliberately finish him off.
The greater danger is player damage while Kelvin is already vulnerable. Stray melee attacks, projectiles or explosive damage can permanently kill him.
If Kelvin is fully dead, the normal command system does not contain a resurrection option. Reloading an earlier save is the cleanest way to restore the original companion if you kill him accidentally.
I would therefore avoid fighting directly over a downed Kelvin. Clear the immediate threat first, then revive him once your own attacks are no longer likely to hit him.
Keeping Kelvin alive also matters beyond resource gathering because his survival affects his presence during the late-game companion sequences.
Can You Change Kelvin’s Clothes?
Kelvin can wear several player-found outfits, but his clothing does not change his abilities or work efficiency.
Use the Take Clothing command while carrying a compatible outfit to change what he wears.
Kelvin-compatible clothing includes the Blazer, Hoodie, Leather Jacket, Silk Pyjamas, Space Suit, Tactical Jacket and Tuxedo.
The clothing choice is cosmetic. A warmer-looking jacket does not make Kelvin gather faster, survive combat more effectively or perform better during winter.
Is Kelvin Worth Keeping?
Kelvin is worth keeping alive because he removes a large amount of repetitive work from a normal playthrough.
His greatest value is not any single command. It is the ability to keep gathering, construction and maintenance progressing while you concentrate on caves, equipment and story progression.
For an established base, I would make Maintain Base his default job. When starting a new settlement, Logs and Finish Structure usually provide more immediate value.
Virginia complements him rather than replacing him. Kelvin handles labour and construction, while Virginia provides the combat support that Kelvin cannot.
