Lone Scientist

Lone Scientist is the title of the main protagonist of Forever Skies' story, and is how the game and its developers refer to the player.

# Immunity Mechanic

The **Immunity** mechanic is the key survival mechanic of Forever Skies. Immunity plays a large part in helping you resist Diseases, as well as other things like determining the effectiveness of Boosters

# The Immunity Circle

Immunity is represented as a composite score of all the player's health parameters, displayed on a circle.

## Health Parameters

* Fatigue
* Health
* Hunger
* Thirst
# Fatigue

The Fatigue Bar is part of the **Immunity** mechanic, and is an indicator for how much **Energy** the player has left. This also dictates how much Stamina the player has available.

With a maximum value of 100\*, Energy will decrease naturally by roughly 1 every 33 seconds, taking about 55 minutes to reach 0. Upon depletion the player will pass out and collapse on the spot, regardless of how inconvenient or dangerous it may be, sleeping until cancelled or until a full sleep cycle is completed.

Energy will not regenerate by itself, and the following means must be used:

* Sleeping, either in a bed by choice, or after being forced to pass out upon bar depletion.
* Eating consumables with a **+Energy** stat, like a Coffee Nut or Old Isotonic Drink.

\*Currently there is a bug where sleeping allows you to go over 100 maximum Energy. This has already been reported and we can expect a fix in the future, but in the meantime for anyone who tries to test against this value, please keep that in mind.

## Stamina

**Stamina** is a subtype of **Energy** that fuels player actions, like sprinting or knife swings. The maximum amount relies on the amount Energy available on your Fatigue Bar, so - if you have 60/100 Energy you will have 60 maximum Stamina. Stamina is displayed as a thinner bar just underneath the Fatigue Bar.

If Stamina goes lower than the amount required to perform an action swiftly, when an action is used, then the action will still be performed but significantly slower than normal. The exception to this is sprinting which simply will not work if you are completely out of Stamina, or is disabled if your maximum amount is less than 20% of the possible bar and is displayed as red.

While it may seem like using up your Stamina results in Energy being depleted faster, it has no effect. Other than its dependent maximum amount, Stamina is separate from Energy.

## +Energy Consumables

# Health

The Health Bar is part of the **Immunity** mechanic, and is an indicator for how much damage the player can receive before dying. This meter has a maximum value of 100.

Health will never decrease naturally or by any means other than damage received, which can happen via the followings methods:

* Falling from extended heights.
* Potentially hostile entities, such as but not limited to Fauna.
* Eating some raw consumables, like Dust Moths.
* Drinking unfiltered fluids like Dirty Water.
* Encountering, or being struck by hazards.

Health will slowly regenerate when the Immunity Circle is above 50%. Other means of restoring health are currently limited to using consumables with a **+Health** stat like a First Aid Kit.

# Hunger

The Hunger Bar is part of the **Immunity** mechanic, and is an indicator for how much **Food** the player has available to use up before dying of starvation.

With a maximum value of 100, Food will decrease naturally by roughly 1 every 22.2 seconds, taking about 37 minutes to reach 0. Upon depletion, you will be notified of extreme starvation, and die about 5 seconds afterwards.

Food cannot regenerate naturally, and must be restored with consumables that have the **+Food** stat.

## +Food Consumables

# Thirst

The Thirst Bar is part of the **Immunity** mechanic, and is an indicator for how much **Water** the player has available to use up before dying of thirst. With a maximum value of 100, Water will decrease naturally by roughly 1 every 17.4 seconds, taking about 29 minutes to reach 0. Upon depletion, you will be notified of extreme thirst, and die about 5 seconds afterwards.

Thirst cannot regenerate naturally, and must be restored with consumables that have the **+Water** stat.

## +Water Consumables

# Immunity Levels

Immunity Level is divided into three distinct states: High (>75%), Medium (50-75%) and Low (<50%). Each state of the Immunity system can affect different aspects of gameplay in different ways.

## Disease Resistance

The higher your Immunity Level, the lower your likelihood to contract a disease after coming into contact with possible sources of infection. With a **High** Immunity Level, it's possible to withstand an infection several times in a row. In the event of successfuly resisting an infection, the suit AI can be heard saying: "Immune system has dealt with the infection".

For more information on what each type of disease can do along with possible sources of infection or cures, see Diseases.

## Booster Hexes

The Immunity Circle houses an additional feature to indicate the ability to use, as well as the effectiveness of, Boosters, known as Booster Hexes that displayed inside of the circle. For more information on boosters and their effects, see Boosters

### High Immunity Level

When Immunity Level is **High** both hexes are highlighted.

Two boosters activated in this state will both work to their full potential, providing their benefits for the full booster duration of ~35 minutes.

### Medium Immunity Level

When Immunity Level drops to **Medium**, one hex becomes greyed out and deactivates.

If two boosters are activated in this state, the most recently activated booster's effect will be prioritized in the active Hex and last for the full duration. Then, the oldest activated booster will be deprioritized and wear out within the next 2 minutes. However, returning to a *High* Immunity Level will return the oldest activated booster to a prioritized state, bringing its effect duration back to what it should be, minus whatever percentage of its duration had passed while deprioritized.

### Low Immunity Level

When Immunity level is **Low** both hexes are greyed out and any booster activated in this state will wear out quickly.

# Story

*"Poor souls. We do this for their sake."*The following article/section contains spoilers.
Not much is known about the Lone Scientist, their past, or their personality. After the encounter in the Underdust, the suit AI refers to the player as Noah, who is referenced various times throughout lore entries in the Story and described as a borderline-insane person who hears voices.

It is difficult to tell if the player IS Noah, or if the AI is confused and calling the player Noah for other reasons.
