The Aurora was a brand-new Alterra Long-Range Capital Ship sent to the Ariadne Arm by the Alterra Corporation to build a phasegate. During a gravity slingshot maneuver around Planet 4546B the Aurora suffered a catastrophic hull failure and leading to it crash landing on the surface of the planet.

Upon crashing, the Aurora plowed into the terrain, unearthing it and leaving small sand hills around the ship. The crash and subsequent explosion resulted in huge quantities of Metal Salvage and Supply Crates being dispersed within the vicinity of the ship, providing useful materials such as Food & Water, batteries, and Titanium. Nine Reaper Leviathans patrol the crash site

Planet 4546B itself is an ocean planet and is said to be smaller than Earth with a breathable oxygen-nitrogen atmosphere. It also harbors two moons, one being very close to the planet, causing frequent solar eclipses. There are three known major ecosystems on the planet: the Crater, Sector Zero, and the Dead Zone, the latter of which covers the majority of the planet. The planet is almost completely covered in water, except for a few islands, and features a variety of submerged, ecologically distinct biomes.

The PDA (Personal Digital Assistant), also sometimes called the Survival PDA, is a multipurpose device that the player keeps with them at all times. The PDA's AI keeps the player informed of their health status and will alert the player when the player has 30 or 10 O2 points remaining, if the player is getting close to dehydration or starvation, or if the player is reaching dangerous temperatures. It also gives useful information to the player when they enter new areas or find new materials.
