# Augmentations

Advances in science and medicine have led to powerful new technologies that allow people to augment themselves beyond normal human capabilities.
There are many different types of Augmentations, ranging from cybernetic to genetic to biological.
Acquiring these Augmentations enhances the user's physical and mental faculties.

Augmentations provide persistent upgrades in the form of multipliers.
These multipliers apply to a wide variety of things such as stats, experience gain, and [hacking](hacking.md), just to name a few.
The effects of Augmentations stack multiplicatively.
Your multipliers can be viewed in the `Character` pages.

## How to acquire Augmentations

Because of how powerful Augmentations are, the technology behind them is kept private and secret by the corporations and organizations that create them.
Therefore, the only way for the player to obtain Augmentations is through [Factions](factions.md).
After joining a [Faction](factions.md) and earning enough [Reputation](reputation.md) in it, you will be able to purchase its Augmentations.
Different [Factions](factions.md) offer different Augmentations.
Augmentations must be purchased in order to be installed, and they are fairly expensive.
They also require [Reputation](reputation.md) with a [Faction](factions.md) before they will let you purchase their Augmentations.

## Installing Augmentations

You will not gain the benefits of your purchased Augmentations until you install them.
You can choose to install Augmentations through the `Augmentations` menu tab, found under `Character`.

Unfortunately, installing Augmentations has side effects.
You will lose most of the progress you've made, including your skills, stats, and money.
You will have to start over, but you will have all of the Augmentations you have installed to help you progress.
This is the game's "soft reset" or "prestige" mechanic.

To summarize, here is a list of everything you will **LOSE** when you install an Augmentation:

- Stats/Skills
- Money
- [Scripts](scripts.md) on all [servers](servers.md) EXCEPT your home computer
- Purchased [servers](servers.md)
- [Hacknet Nodes](hacknet_nodes.md)
- [Company](companies.md) / [Faction](factions.md) [Reputation](reputation.md), but you gain [Favor](reputation.md).
- Jobs and [Faction](factions.md) memberships
- Programs
- [Stocks](stockmarket.md)
- TOR router

Here is everything you will **KEEP** when you install an Augmentation:

- Every Augmentation you have previously installed
- [Scripts](scripts.md) on your home computer
- [RAM](ram.md) / Core Upgrades on your home computer
- [World Stock Exchange account](stockmarket.md) and [TIX API](https://github.com/bitburner-official/bitburner-src/blob/dev/markdown/bitburner.tix.md) Access

## Purchasing Multiple Augmentations

You do not have to install an Augmentation right after you purchase it.
You can purchase as many Augmentations as you'd like before you choose to install them.
When you install your purchased Augmentations they will **ALL** get installed at once.

There are a few drawbacks to this, however.
First, obviously, you won't gain the benefits of your purchased Augmentations until after you install them.
Second, purchasing multiple Augmentations before installing them will cause the Augmentations to get progressively more expensive.
When you purchase an Augmentation, the price of purchasing another Augmentation doubles.
This multiplier stacks for each Augmentation you purchase.
Once you install your purchased Augmentations, their costs are reset back to the original prices.
You can only purchase each augmentation once, with the exception of `NeuroFlux Governor`, which can be purchased infinitely at increasing cost.
