I found these images recently and immediately thought they would make a great level for a Half-Life 2 Mod.

It could be part of a large puzle, meaning that certain actions have to be performed before the ship reaches the dock, get the electricity working, open the gears etc.

I have no idea where this is, so if you have any information please contact me.

Here is another collection of images that I think would make either a great level or at least provide inspiration for one.

These images come from Russia. To my knowledge they are not part of the normal underground system.

Any extra information about them would be appricated. If you know of similar types settings please contact me.

CERN is the European Organization for Nuclear Research, the world’s largest particle physics centre.

Here physicists come to explore what matter is made of and what forces hold it together.

I can’t remember where I first found these images but I remember being amazed and thinking this would make a cool level!

It is some kind of water control system for floods or tsunamis etc.

It seem that there are guided tours available and if I ever visit Tokyo then this will be on the top of my list of places to visit!
