Our take on Project Castaway

The store presentation gives substantial attention to Pacific scenery, weather, and isolation, while the core play is a repeated cycle of gathering, hunting, crafting, travel, and survival management. The supernatural threat is presented as a consequence of neglected sleep and sanity rather than a separate exploration focus.

What is Project Castaway?

Project Castaway is a survival crafting game set across the Pacific Ocean.

Players take the role of a stranded castaway, traveling between islands by raft, collecting materials, hunting animals, gathering food, cutting trees, and searching wrecked ships. Resources support construction of shelters, rafts, and a base for protection and survival. The game includes changing weather, cold nights, swimming, and exploration of islands with different resources. Survival also involves sleep and sanity management: neglecting these needs can lead to apparitions that attack the castaway. The structure centers on expeditions across the ocean, resource collection, construction, and maintaining the character while isolated among the islands.
