The XSTN-K upgrades are a series of legendary artifact upgrades that are seemingly related to the Xsotan. These upgrades are typically rewards for major quests or boss fights, and are used as extremely powerful upgrades, and to open up the portal to enter The Core.

Each XSTN-K gives a specific and unique buff that is related to the method of obtainment when equipped and, typically, permanently installed. As an example, fighting Boss Swoks, a pirate kingpin, yields an Armed Turret Slot Artifact, XSTN-III.

Progression Use[ | ]

When searching hidden mass sectors close to the barrier, the player may find a structure of 8 asteroids in a circle, numbered from I to VIII. The player is then intended to create 8 distinct ships and put one of each Xsotan Upgrade in a separate ship and place the ship in front of the asteroid with the number of the artifact the ship has. When all 8 ships are placed next to their respective ominous asteroids, a wormhole to cross The Barrier is created, and the endgame begins.

Note that you while need to permanently install all artifacts (with the exception of the Exodus Artifact, XSTN-I) for them to work as upgrades, you do not need to permanently install them to open the wormhole.

The player will also not receive any quests relating to any of the XSTN-K upgrades unless they appear as obtained in the player profile tab. This can be problematic if an upgrade is collected in an alliance ship and is immediately put into the alliance vault, rather than the player's personal vault. This can easily be fixed by transferring the items form the alliance vault into the player's vault and back again.

Subsystems[ | ]

Below is a list of each Xsotan subsystem and their statistics.
Every artifact is of Legendary rarity and has a price of 10,000 credits except for the XSTN-K IV, which has a price of 3,000,000 credits.
Each subsystem can only be installed once per craft, meaning it is possible to have many of each subsystem across an entire fleet, but only one per ship.
All artifacts do nothing unless permanently installed except for the XSTN-K I, which does not need to be permanently installed to function.
