The person that created the original sprites also made 4 other doors that were smaller - all of which were epic, but hey, why not choose to doorify the most epic of them all?

In my original thread, I credited lololn00b for the sprites and left a link to his work, however it's been blitzed.

Indeed. Those two + the silo and brain vault 3 are all I've got.

That was Maximdude, and these doors were intended to be included in his MDHQ map long time ago. Although they were just static objects back then.

Yea it was maxim - I posted a link to his converted HQ. The doors all look of the same style as that big one.

I happen to recall maximdude making these for his base, as well.

Thats the best Door ever.

I agree. Made some changes to it myself though; a few pretty stairs around the door and changed the material of that door to concrete when it dies. Otherwise you can just walk through it.

Is this what you need for the BG?

While I can use that, you should be aware you've missed the actual background there. =P

Eh i just threw that together in the middle of converting two scenes to B20.

There is an updated version of these doors in the BMCP, for those interested. It adds the tunnel door and the old doublesized rocket silo. I'll update the mod here after fixing the tunnel door's background.
