Java, the brew of the world!

I could, and will, kill for a cup of Java...

— Employee #38208-1A

Java is a coffee-like drink and powerful stimulant that comes laced with a cocktail of nootropics and enough caffeine to set the most stagnant heart aflutter. It is the most popular brew in Megacorpolis, consumed every day by millions of chronically sleep-deprived employees to stay awake and alert. It probably doesn't contain any experimental or rejected combat drugs.

Everyone drinks Java - except for those insufferable Contrarians who'd very much and at length like you to know that they do not.

Java has the same color and smell as coffee but with a sweeter taste that help consumers enjoy their delicious and refreshing cup of Java. The drink is ubiquitous, found everywhere in the Megacity from its highest corporate quarter to the poorest sector-slum. Many corps even provide it free to their employees as a means of keeping up production and a nice, even level of manic energy. Even momentary shortages have triggered panic and riots in the past, or the consumption of questionable alternatives.
Many employees need a cup just to get out of bed, which is just how Big Java likes it.

Javamania

With a taste this great, who wouldn't want more?

Java has it all: great taste, refreshes the mind, and a high chance to cause a crippling addiction. Everyone loves Java, but Javamania can turn such corporate-pleasing enthusiasm for the drink into a degenerating illness that hurts productivity first and the health of the addicted second. Even before the mutations start, Javamania leads to debilitating headaches, fatigue, and a hair-trigger when they go too long without a fresh, delicious cup of Java.

Once in its throes, a Javamaniac will do anything it takes to get that cup of Java, and god helps anyone who gets in their way. Addicts often roam from Javamat to Javamat to gorge themselves on as much Javas as their bodies can hold, and frequently past that point.
Citizens are recommended to hand over their Java if accosted by a Javamaniac, but most take a 'from my cold, dead hands' attitude to that suggestion.

Some Javamaniacs have been known to consume the drink at such a rate that they drown in it.

Despite all this, fatalities remain infrequent, as a consumer with debts to pay find that medical attention can be both prompt and proper.

The Original

Since its inception, hundreds of different brands of Java of varying quality have emerged to compete for market share. The original inventor, the Java Inc Megacorporation, still dominate space with a combination of brand recognition and brutal murder.
Though initially a military-tech corporation specializing in combat drugs and chemical warfare, it was their foray into the consumer market that elevated them to megacorpdom.

Javamats

Found at almost every corner of the megacity, Javamats are automated booths that dispense the brew at affordable rates. Citizens flock there to buy their Java, with every corp having its own style and selection of drinks.
Some are on occasion earmarked to mix their product with other drugs or pharmaceuticals as a cost-effective way of testing, but it's probably safe.

Javabominations
Some consumers really enjoy their Java and some few come out of throes of Javamania with a singular thought: that was great!
When a consumer has devoured enough Java and gone through so many Javamania episodes, they become a Javabomination. These creature-things have been changed by the brew into addled, strung-out versions of themselves with surprising strength and speed. They are dangerous, more creature than consumer, who will go to any length to get more Java.

Popular Brands

Not all brands of Java are created equal. Corporations have tweaked their formulas (or marketing campaigns) to stake their claim on the Java market. Some are more popular than others, with feuds between consumers about which is the best often leading to bloody riots and snarky youtube videos in equal measures.

Dhe-licious Java

A more expensive type of Java, served cold. Frequently found in the hands of people with some wealth and a desire to flaunt it.

27-Bean Brew

A sugary sweet Java that does in fact not contain any beans, coffee or otherwise. Gives off light in the dark, supposedly by design.

Anz-mazing Java

A particularly cheap brand that still claims it doesn't harm the consumer. Its taste is described as "nail-polish remover"-y.

What it says on the tin. You read the EULA, you know what you're getting yourself into. Delicious but deadly.

Cup of the Covenant

Marketing will often claim drinking it is delightful enough to be a religious experience - and you'll probably get to meet god if you have more than two cups in a day.

Storm Charged Brill-iance

Absolutely, positively not made from the ground-up remains of failed Best Friends Forge genetic experiments. Makes you a rebel, according to their marketing, which they say is cool so buy it.
