Underground bases?

[Erasus 1]

I hear that about of the underground bases idea for the standalone, meanwhile playing in takistan i see these edifications, like fallout 3?

PD: sorry bad english.

Hmm, I don't know. I think the idea was more like a manhole or hatch door.

Like this maybe.....?

I had the impression that it would be built with a shovel, like the entrenching tool that was in the game which had no use. So maybe like the rat holes that were all over vietnam, and i think that those doors in the pictures have been in the game since it was made, i know for a fact the first one is in the campaign.

I was thinking along the lines of Spirit's post; pre-created underground areas like basements, cellars or shelters that can be customized and expanded.
