Endure Island

Endure Island is a survival game about investigating a virus on a deserted island where large numbers of infected people repeatedly appear and disappear. You belong to an organization investigating the phenomenon, and must uncover the virus’s mystery and eradicate it while surviving long enough to return alive.

Research the virus

The virus causes the island’s abnormal events. It continually mutates and multiplies, making the environment increasingly hostile. You explore different areas to collect items containing the virus, study its characteristics and interactions, and bring your findings back to headquarters. Research takes time, but you can speed it up by working at multiple facilities at once or injecting a large amount of virus into specific equipment.

As the story progresses, you can release viruses from your research facilities into other environments. For example, releasing a virus found in the forest into the city can cause changes that would not normally occur there. You can use viruses to:

• Promote proliferation and improve investigation efficiency.
• Trigger mutations through interactions between different viruses.
• Use viral interference to mitigate environmental degradation.

Some viruses cannot be obtained through exploration alone, so discovering how viruses interact is important. Releasing them recklessly can also make the environment much harsher.

Escape the island

Your main objective on each expedition is to survive and return from the island. Use the radio at a virus research facility to call a helicopter, then hold out while it makes its way to you. If you fail to escape, you lose everything gained during that exploration, so call for help before conditions become too difficult to survive.

The island’s virus repeatedly appears and disappears, and each new expedition begins from the same initial conditions. Items found on the island may carry viruses and cannot be brought back to headquarters, and your equipment resets to its initial state.

Carry knowledge forward

Knowledge gained by completing quests, equipment you repair and doors you unlock are saved as memory and carried into the next investigation. This memory can lead to new scenarios in future explorations, so quests progress alongside virus research.

Mutants and progression

Virus mutations create mutants that spread contamination. They can appear frequently depending on the virus’s state, and prolonged close combat should be avoided. Stabilizing a mutation can prevent mutants from appearing.

A skill tree lets you gain abilities, improve stats and expand the range of items you can craft. Progress in virus analysis unlocks weapon mods and virus inoculation features, broadening the ways you can play.
