About X4: Foundations X4: Kingdom End
X4: Kingdom End is the fourth expansion for X4: Foundations. It reunites you with the Boron, adds their ships and systems, and follows a multifactional expedition investigating a mysterious jump gate in Heretic's End.
The expedition
Flickering lights from a previously inactive jump gate cause a stir. You join an expedition formed through cooperation among different factions to investigate the phenomenon. Its members must work together despite their very different perspectives.
Boron ships
The expansion adds a range of Boron ships in different classes. Their designs feature fluid shapes and animated, wavelike shells. The Ray is a destroyer with a delicate construction; although the Boron are normally peace-loving, they will defend themselves when necessary. The Shark is an XL carrier whose smaller ships can dock and launch from its sides, giving it an advantage in battle.
