Licensing: Fair use for Xen (Half-Life)
This is a screenshot of a copyrighted video or computer game, and the copyright for it is most likely held by the company or person that developed the game. It is believed that the use of a limited number of web-resolution screenshots

for identification and critical commentary on the computer or video game in question or the copyrighted character(s) or item(s) depicted on the screenshot in question on the English-language Wikipedia, hosted on servers in the United States by the non-profit Wikimedia Foundation, qualifies as fair use under United States copyright law, as such display does not significantly impede the right of the copyright holder to sell the copyrighted material, is not being used to generate profit in this context, and presents ideas that cannot be exhibited otherwise. See Wikipedia:Non-free content and fair use rationale.

To the uploader: please add a detailed fair use rationale for each use, as described on Wikipedia:Image description page, as well as the source of the work and copyright information.

The poster of the rationale asserts that the image qualifies fair use for the following reasons:

Valve Corporation has not release location-specific images into public domain. The image is necessary to describe the appearance of a unique creature and location in Xen (Half-Life); nothing else. The screenshot is not intended to hinder the copyright owner's ability to sell the game. This image is a game screenshot.
