Assuming most of you visit the TTLG forums regularly,
You have probablly seen some portion of the squable regarding
a project from late 2004, early 2005.

I dont really want to repeat it here.

Suffice to say that the attached is a Doom3 PK4.
It is a reproduction of the Citadel Level One.
It includes assets generated by Lanael's tools
released publically on Jan 31st, 2006 on his blog.
http://lanael.free.fr/dotclear/index.php

It includes complete architechture for level one,
working doors and lifts, and grav lifts. And many other features.
You can shoot cameras, but it can be tricky...

Unlike a normal D3 map, you must double-click to activate doors,
and buttons etc.
Unlike the original SS1 you cannot double-click the whole door,
you must double-click on the activation panel. For medical doors
this is the blue/yellow lit panel. You will know it because the
crosshair will disappear, and the ubiquitous D3 squeak will happen.

To install just place the PK4 file in your <doom3>/base directory.
PLEASE NOTE:
If you have previously installed Lanalel's assets, move any FOLDER
in your <doom3>/base directory to a <doom3>/base/_disabled.

Once the game is started, drop the console, and type "map citadel/level1.map"
You should see a familar place in a few seconds.

To uninstall delete the PK4 file.
Move any folders from the <doom3>/base/_disabled
back to the <doom3>/base.

It's not a lot but it is more than nothing.
Enjoy...
