Watch 30 Days on Ship TrailerWHAT IS 30 DAYS ON SHIP?
30 Days on Ship is a first-person survival simulation game developed by Madnetic Games and published by PlayWay S.A. Built on Unreal Engine 5, the game puts you in the shoes of a castaway stranded on a colossal wrecked container ship in the Pacific Ocean.
Your 30 Days on Ship goal is straightforward yet brutal: survive for exactly 30 in-game days until rescue arrives. The ship is loaded with hundreds of shipping containers — each one a mystery blind box filled with unconventional items like TVs, motorcycles, fridges, and drones. You must creatively repurpose these items to build shelter, craft tools, find food, and defend against storms, wildlife, and pirate raids.
30 Days on Ship features a unique mental health system — isolation and psychological stress are as dangerous as hunger and physical threats. With planned support for up to 4-player online co-op, you can team up with friends to divide tasks, share resources, and face dangers together.
