Sons of the Forest is Endnight Games' survival horror sequel set on a remote island where your helicopter crashes during a rescue mission. With your AI companion Kelvin and the potential ally Virginia, you must build shelter, find food, and survive against cannibals and mutants while uncovering the island's mysteries. The game features a fully simulated season system, advanced building mechanics, and 3D printer technology scattered across the island.
This guide covers everything you need: core mechanics, the best builds, equipment worth investing in, location progression, and the tips that actually make a difference.
Core Mechanics
companion AI
Kelvin is a deaf AI companion who follows orders via a notepad interface. He can chop trees, catch fish, gather sticks/rocks, build structures, and carry logs. Virginia is a three-armed mutant woman who becomes a companion if you don't threaten her — she can equip weapons and fights alongside you.
3D printer crafting
3D printers found in bunkers and caves print advanced items using Printer Resin. Items include arrows, flasks, grappling hooks, and the tech armor set. Resin is limited, so prioritize essential items. The printers are a primary reason to explore bunkers.
cave exploration
Caves contain key story items, the best weapons, and connect to the bunker network. Bring a flashlight or torch, multiple health items, and be prepared for mutant encounters. Some caves require the Rebreather (underwater sections) or Rope Gun (zipline traversal) to fully explore.
seasons
The game simulates spring, summer, fall, and winter. Winter reduces food availability, lowers temperature (requiring warm clothing or fires), and changes enemy behavior. Spring and summer have abundant berries and animals. Building a heated shelter before winter is critical for survival.
shelter building
Building uses a hybrid system: a survival guide provides pre-designed structures, or you can freeform-build with logs, sticks, and tarps. Log walls block cannibal attacks. Defensive walls with spike traps protect your base. Rain and cold affect your character inside unroofed structures.
Builds Overview
| Build | Tier | Playstyle | Key Stats |
|---|---|---|---|
| Kelvin Commands | S | Treat Kelvin as a resource gathering bot — assign tasks before leaving base, collect results on return. | Keep Kelvin alive > efficient task assignment > base location with resources |
| Virginia Companion | A | Be non-threatening to Virginia, arm her once befriended, let her fight alongside you. | Patience (don't scare her) > weapon for her > GPS tracker |
| Solo Survival | B | Fortify your base, venture out during daytime only, explore caves with full preparation. | Food/water security > base defense > weapons > exploration |
| Defensive Builder | A | Build walls and traps until your base is a fortress, then explore from a safe home base. | Log supply > defensive structure design > trap placement |
| Cave Explorer | A | Prepare heavily, enter caves, collect key items, advance the story. | Equipment from caves > combat readiness > supplies for long expeditions |
Kelvin Commands (S-Tier): Maximize Kelvin's usefulness by ordering him to gather resources constantly. He can chop trees, collect sticks, catch fish, and fill log holders. Setting him to gather while you explore or build doubles your productivity. Keep him away from combat — he can die permanently.
Virginia Companion (A-Tier): Virginia approaches your camp if you don't aim weapons at her. Over multiple visits, she gains trust and eventually equips weapons you leave on the ground near her. She's a powerful combat ally with the Shotgun or Pistol. GPS tracker lets you find her on the map.
Solo Survival (B-Tier): Playing without companions (or after they die) is the true survival horror experience. Resource management becomes critical. Build defensively with spike traps and walls. Focus on the Shotgun and Crossbow for combat efficiency. Night becomes terrifying.
Defensive Builder (A-Tier): Focus on building an impenetrable base with log walls, spike traps, and elevated platforms. Defensive builders can survive any cannibal raid. Combine with Kelvin's log gathering for efficient construction. The tree house design is nearly unraidable by AI.
Cave Explorer (A-Tier): Prioritize cave exploration for story progression and best equipment. The Rebreather, Rope Gun, Shovel, and Katana are all found in caves. Cave runs require preparation — bring flashlight, meds, and food. Caves contain the game's most intense horror moments.

Equipment Guide
| Equipment | Why It Matters | Best For |
|---|---|---|
| Shotgun | Found in a grave on the western beach (dig with Shovel). | Solo Survival, Virginia companion weapon |
| Pistol | Found in a life raft near the coast. | General purpose, Virginia companion backup |
| Chainsaw | Found in a cave — primarily a resource gathering tool that cuts trees instantly. | Defensive Builder — resource gathering |
| Katana | Found deep in a cave that requires the Rebreather and Rope Gun to access. | Cave Explorer, melee combat |
| Crossbow | Found in a cave or crafted from materials. | Stealth gameplay, ammo conservation |
Shotgun: Found in a grave on the western beach (dig with Shovel). Devastating at close range against cannibals and mutants. Limited ammo — found in crates and on bodies. The best weapon for cave encounters where enemies are close.
Pistol: Found in a life raft near the coast. Reliable mid-range weapon with good ammo availability. The silenced variant (Pistol Rail attachment) reduces cannibal alert. Give the extra to Virginia for a ranged combat ally.
Chainsaw: Found in a cave — primarily a resource gathering tool that cuts trees instantly. Also usable as a devastating melee weapon. Requires fuel. The fastest tree-cutting tool, making base building dramatically faster.
Katana: Found deep in a cave that requires the Rebreather and Rope Gun to access. The best melee weapon with fast attack speed and high damage. Lightweight and durable. The reward for successful cave exploration.
Crossbow: Found in a cave or crafted from materials. Silent ranged weapon with retrievable bolts. Perfect for stealth gameplay and picking off cannibals without alerting the camp. Lower DPS than the shotgun but infinite ammo if you retrieve bolts.
Location Progression
| Location | Level Range | Key Rewards |
|---|---|---|
| Beach Camp | Day 1-5 | Fish, turtles (shells for water collectors), basic resources |
| Mountain Lake | Day 3-15 | Fresh water, deer, berries, abundant logs, central location |
| Cannibal Village | Day 5+ | Clothing, food, meds, crafting materials, enemy skulls for effigies |
| Underground Caves | Day 5+ (with preparation) | Rebreather, Rope Gun, Shovel, Katana, Crossbow, story progression |
| Snowy Mountains | Day 20+ (endgame) | Endgame story bunkers, unique enemy encounters, final story content |
Beach Camp: The coastal area near your crash site. Provides easy access to water, fish, and basic materials. Good starting base location but lacks logs (few trees near beaches). Cannibals patrol less frequently along the coast.
Mountain Lake: An inland freshwater lake surrounded by forest. Ideal base location with access to fresh water, abundant trees, deer, and berries. Central location for reaching caves in any direction. The most popular base location.
Cannibal Village: Hostile settlements found throughout the island. Contain loot like clothes, food, meds, and sometimes weapons. Raiding villages provides quick gear but triggers increased cannibal aggression in the area.
Underground Caves: The cave system contains all key progression items (Rebreather, Rope Gun, Shovel, Katana). Each cave has unique enemies, from basic mutants to massive baby-shaped horrors. Multiple entries with different difficulty levels.
Snowy Mountains: The northern mountainous region with cold temperature danger and stronger cannibal variants. Contains endgame cave entrances and story content. Requires warm clothing or constant fire management to survive.
Tips That Actually Matter
- Kelvin can chop trees and fish for you endlessly. Set him to tasks before exploring — you'll return to a pile of logs and fish.
- Build near a stream for infinite water. Streams provide drinking water and are plentiful across the island.
- 3D printers give arrows, flasks, and tech gear. Prioritize the grappling hook and arrows early. Printer Resin is limited, so plan your prints.
- Virginia becomes a companion if you don't scare her. When she approaches your camp, don't look at her aggressively or aim weapons. After 3-4 visits, she'll stay permanently.
- Log sleds carry multiple logs at once — build one immediately to speed up base construction. Kelvin can also fill log holders.
- Cannibal aggression escalates based on how many you kill and how long you've survived. Building effigies (from cannibal body parts) near your base deters patrols.
- The Rebreather is needed for underwater cave sections. Find it in the cave near the beach with the blinking GPS locator. Bring a weapon for mutants inside.
- Drying racks preserve meat indefinitely. Build several near your base and stockpile dried meat before winter when hunting becomes harder.
- Stick traps and bone traps around your base perimeter trigger on approaching cannibals, dealing damage and slowing raids.
- The GPS tracker on your arm shows key points of interest as pulsing green dots. Follow them to progress the story and find important items.
Common Mistakes to Avoid
- Threatening Virginia when she first appears — pointing a weapon at her or acting aggressive causes her to flee permanently. Let her approach on her own terms.
- Not building a shelter before the first night — cannibals are more aggressive at night. Even a basic tarp shelter gives you a save point and rest.
- Entering caves without proper preparation — no flashlight, low health, no food or water. Caves are long, dark, and filled with enemies. Prepare fully before entering.
- Ignoring Kelvin's usefulness — many players let him follow aimlessly. Assign him tasks constantly: gather sticks, chop trees, catch fish, build walls.
- Building a base in the open without defensive walls — cannibal raids will destroy an undefended base quickly. Log walls and spike traps are essential.
Frequently Asked Questions
