Following a severe plane crash caused by unknown circumstances en-route to Japan for a business conference, the player wakes up to find that they are the lone survivor of the ordeal. With nothing but your skills and what you can find in the environment, you must survive in the islands of the Pacific.
Throughout their journeys, the player will encounter many exotic views, many hazards and many of the ocean's fauna - lush coral reefs, vast sights, an abundance of fish and marine life, as well as more significant features such as sharks and even whales. Though these sights may capture the awe and attention of the player, they must steer clear of many things; some may poison, some may cause illness, while others will outright kill the player.
Survival on the islands will determine whether or not the player has the necessary skills needed to thrive on such a vast but empty environment. The player will need to keep themselves satiated on food and water in order to prevent any illnesses or diseases from being contracted. Crafting also becomes a key skill when surviving, as different tools are needed for different purposes - axes and hammers can be used for building.Shelters can be erected to keep the player safe from environmental hazards, and crude vehicles can be crafted to aid the player in travel.
Along with using the available resources found on land, the player may also choose to dive deep in search of supplies left behind by past explorations. The leftover remnants of ancient ships and crashed planes can be discovered strewn about the ocean's floor; within them, their cargo. Players are able to make use of these supplies to aid them in their survival, and may also possibly increase their chances of a rescue. However, exploring the depths comes with a risk, as deadly marine life can be found dwelling the waters around them, putting the player in danger.
