From Black Mesa: Wiki

Overview

Xen, also referred to as "the borderworld," is an alien dimension which is the source of the invading aliens in Black Mesa. It is also the name of a chapter in the game.

Chapter Summary

After successfully jumping through the portal, Gordon Freeman is teleported to Xen, which is the homeland of the aliens. Enemies are much less aggressive here. Gordon must use the Long Jump Module in order to safely descend to the island below (which is obviously only a part of Xen). Once there, he fights to the center, avoiding stationary zappers, and using small pools which replenish health. Once at the center, he opens up three "ports", and releases three mysterious items. These items fly around and land, one in each port. This causes a beam to be formed in the center platform. Going through this beam will teleport Gordon to the chapter: Gonarch's Lair.

Geography

Xen is made up of small or medium floating rocks surrounding large landmasses. These appear to be suspended over open space, and not physically connected in any way. Certain Xenian flora can be utilized as teleporters connecting to other large Xenian landmasses.

Flora and Fauna

Xen has a diverse set of lifeforms inhabiting it.

Xenian Phenomena

Pools of healing water can be found at various areas of Xen. The pools are extremely small and shallow, and their healing properties seem to be exclusive to the pools and not to Xenian water itself, as larger bodies of water seen on Xen have no such properties.

Media

The developers will not reveal anything about Xen until the mod release. [1]
