Wolfenstein-Type Catacombs Under Odessa

I love the Internet and now reddit.  I learn about things I wouldn'ta otherwise.  Who knew that the catacombs of the Wolfenstein saga (see! I brought it home!) do exist, under Odessa:

Apparently, death in these catacombs is not uncommon.  Note to Russian teens dared to go in there -- don't!!!
Eye Candy ... ok fine, I made alink this time....

They do remind me of the catacombs in Return to Castle Wolfenstein:

They apparently stretch throughout the underneath of Odessa

(yes, scarfing most of this from reddit comments, ty redditors!)

What a way to die, in endless, underground passages....

If you go down in there, this could be you....
