The Forest — Achievement Walkthrough

Survive your first night on the peninsula. Build a small fire and a basic shelter after the plane crash, then hold out until morning.

Co-op only. Sleep at the same time as another player in a group sleep so the party rests together.

Co-op only. Revive a downed teammate once — run to a knocked-out player and hold the revive prompt.

Survive five in-game nights. Keep food, water and a defensible shelter going and this unlocks naturally as you play.

Cut down 100 trees with an axe. Chopping wood for building racks this up quickly.

Kill a bunny. Bunnies hop around the forest — hit one with any weapon. Works alone in single player or together in multiplayer.

Eat an enemy. After killing a cannibal, eat part of the body (your survivor can eat limbs). Sanity drops, so use it sparingly.

Multiplayer only. Share a food or drink item with another player.

Kill a bird with an arrow. Craft a bow and arrows, then shoot one of the small birds that land in the forest or on the beach.

Craft and wear the stealth armour, which is made from rabbit hides and other hunted materials — then equip the full set.

Use the compass. Find the compass among the plane wreckage or in luggage, add it to your inventory, and use it.

Sleep on the yacht. Find the wrecked yacht on the coastline and rest there instead of a shelter.

Single player. Kill 100 cannibals over the course of your playthrough — combat-heavy play gets you there.

Set off 20 bombs. Craft bombs from collected electronics and explosives and detonate 20 of them.

Single player. Go more than 10 days in a row without killing any cannibals. Play defensively, avoid combat, and rely on walls and stealth.

Co-op. Revive 10 downed teammates across your co-op sessions.
