Citadel vs. Interloper

[kirovman]

I didn't notice this specifically mentioned before, but I'll state what I have observed.
The interior of the citadel looks a lot like the interior of the interloper.

You see a look of hidey holes in both (both square cut), and the citadel manufactures Overwatch forces, while interloper manufactures Alien Grunts. Vortiguants are slaves inside, while Stalkers are slaves in the citadel.
They both have crazy health recharging places, like the suit chargers which take your armour to 200 and in Xen the blue pods which recharge your health.
And at the top of interloper you have to go through a teleporter to get to Nihilanth. Well at the top of the citadel there is a teleporter too. With lots of moving platforms and other weird things.
Anyway I havent played HL1 in a while, but I think I might just to go back to interloper and see some more similarities.
If anyone else saw similarities, please list them.

They were conquered by the same organization/race, what did you expect?

Yeah I know, it's just kind of cool to realise the similarities, but they are not exactly the same, because they are adaptations of the technology of the race they conquer.
For earth, it is computer and electronic technology,
for Xen it is more biological.
But ultimately the underlying technology is sculpted into the combine's own design, to meet their purpose.
