All right, I've been thinking, when life gives you lemons, don't make lemonade! Make life take the lemons back! Get mad! I don't want your damn lemons! What am I supposed to do with these? Demand to see life's manager! Make life rue the day it thought it could give Cave Johnson lemons! Do you know who I am? I'm the man whose gonna burn your house down - with the lemons!

GLaDOS: Yes Sir MR JOHNSON

In the late 20th century, it was discovered that under the icy, irradiated surface of Jupiter's moon Europa lies a vast sea capable of sustaining life. This discovery sent shockwaves through the scientific community.
In the year 2022, the first manned space flight arrived on Europa to discover that the moon was indeed already sustaining life, in the form of hostile sub-aquatic fauna. Besides the wildlife, the researchers faced gruelling difficulties posed by the dangerous radiation emitted from Jupiter and the intense cold and tremendous pressure of the Europan ocean.

Despite all their hardships, Earth-born colonists were able to construct a handful of habitable outposts where a new way of life developed over many decades. A new system of governance was formed by a coalition of the largest, most influential cities on the moon. Different industries made their mark in the new world, including mining, manufacturing and chemical laboratories.

Over the years, Europan society became more and more dissociated from Earth. Fifty years ago, contact was lost entirely, and no more supply ships have arrived since.

Sub-aquatic travel and vehicles are in a key role in this new society, scouting for new inhabitable locations, protecting citizens from creature attacks and establishing supply lines between stations as humanity ventures ever deeper to evade the lethal radiation from Jupiter above. The life of a crewmember aboard one of these submarines is a lucrative one, albeit dangerous and often short.
