Assembling the mysterious alien artifact in Sons of the Forest is one of the most rewarding late-game objectives for survival enthusiasts. Hidden deep within treacherous subterranean caves and high-tech bunkers across the island, seven distinct pieces must be recovered to unlock powerful supernatural abilities. This comprehensive guide provides step-by-step navigation insights to help you locate every piece and complete your ultimate collection efficiently.

Essential Gear Needed Before You Begin

Before embarking on your hunt for the artifact pieces, thorough preparation is crucial for surviving the island's darkest caverns. You will primarily need traversal tools like the rope gun and the rebreather to navigate flooded passages and deep abysses. Carrying adequate weapons, medical supplies, and explosive charges ensures you can deal with aggressive mutant encounters along the way.

Navigating Western and Coastal Caverns

Several artifact fragments are concealed inside cave systems situated along the western coastline and near inland river networks. For instance, entering the coastal cave system requires following narrow passages, descending ropes, and breaking wooden barriers to access hidden chambers. Exploring the western rope gun cave demands careful combat strategies to clear dangerous mutants before descending deeper toward the treasure.

Exploring Northern and Mountainous Caves

Venturing toward the northeast region of the island brings players into contact with deep mining shafts and flooded tunnels. In these locations, using your rebreather is mandatory to submerge through underwater caverns that lead directly to hidden artifact pedestals. Always inspect side paths and breakable barricades, as valuable blueprints and essential survival items are frequently placed nearby.

Securing Eastern Bunkers and Final Pieces

The remaining artifact pieces reside within high-security luxury bunkers and deep underground facilities on the eastern side of the map. Navigating these modern subterranean structures requires keycards and tactical awareness as you clear rooms populated by hostile mutants. Once all seven individual fragments are collected, you can combine them through the crafting menu to construct the completed device .

Unlocking the Full Power of the Artifact

Once assembled, the completed artifact offers unique gameplay functions that drastically alter your survival capabilities on the island. Players can toggle between different operational modes to teleport across map points or turn structures into solafite-plated defense systems. Mastering these features provides significant advantages when defending your base or exploring end-game challenges.
