Endure Island

Basic Explanation

On a deserted island, there was a repeated phenomenon of large numbers of infected individuals appearing and then disappearing. As a result of the investigation, it was discovered that a virus was the cause, and the organization to which the protagonist belongs began an investigation.
The player’s goal is to uncover the mystery of this virus and eradicate it.

This game is developed using Unreal Engine, and we have released videos explaining the development process up to version 0.1 on YouTube. We hope this will be of some help to anyone interested in game development.

Virus Research

The abnormal phenomena occurring on this deserted island are caused by the virus. It continuously mutates and multiplies, gradually making the environment more hostile.
The player's objective is to research and eradicate this virus.

First, you must explore various areas and collect items from which the virus can be extracted for research.
Your role is to understand the virus's characteristics and interactions, and then bring the results back to headquarters.

Research takes time, but you can speed up the process significantly by conducting research simultaneously at multiple facilities or by injecting a large quantity of the virus into specific equipment.

However, you can't begin anything without first acquiring the virus. Players won't just wait around either.
As the story progresses, you'll be able to release the virus from your research facilities.
For example, you can release a virus found in the "forest" into the "city," causing changes that wouldn't normally occur in that environment.

• Promote virus proliferation to improve investigation efficiency.
  
• Trigger mutations through interactions between different viruses.
  
• Utilize virus interference to mitigate environmental degradation.
  

Since there are viruses that cannot be acquired solely through exploration, it's crucial to uncover their interactions and continue your research.
However, be careful—recklessly releasing viruses can quickly make the environment much harsher.

Escape

The player always has one most important goal: to survive and return from the deserted island alive.
If you fail to make it back, you’ll lose everything you've gained from the exploration.

Call a helicopter via the radio attached to the virus research facility and escape.
However, it will take time for the helicopter to arrive, so act before the situation becomes too difficult to survive.

The virus on this deserted island has the characteristic of repeatedly appearing and disappearing, so the next time you explore, you'll start from the same initial conditions.
Moreover, items you obtain on the island likely have viruses attached, so you can't bring them back to headquarters.
Your equipment will also reset to its initial state.

Memory

Knowledge obtained by completing quests, repaired equipment, and unlocked doors are saved as "memory" and carried over to the next investigation.
This memory can lead to the development of new scenarios in future explorations, so be sure to actively progress through quests alongside virus research.

Mutants

Mutants are created through virus mutations.
They spread contamination around them, so long-term close combat should be avoided.
Mutants appear frequently depending on the virus's state, but by stabilizing the mutation, you can prevent their appearance.

Progression

Players can grow through the skill tree, acquiring new abilities, enhancing their stats, and expanding the range of items they can craft.Additionally, as virus analysis progresses, weapon mods and virus inoculation features will be unlocked, significantly broadening the scope of gameplay.
