Steam Summer Sale 2020 Citadel Core Profile Background

[Turn44]

So I recently traded in some points for a HL2 Profile Background named 'Citadel Core".
I then searched for the matching concept art of it on the Combine OverWiki.
Since I couldn't find a match for it neither on the 'Citadel' nor on the 'Citadel Core' article I searched around on the 'Air Exchange' article.
This is the closest match I got.

Incidentally, I was amused that, apparently due to the fact that Valve didn’t have any images that could be put on the background, they just took the Viktor Antonov's concept arts from 2001, when HL2 was a dark and depressive game and renamed it to fit with release lore. These 2 concept arts were made for early Depot and Air Exchange.

Or some valve employee was charged with slapping some stuff up for HL2, saw the concept art and thought, looks right to me
