This is pretty exact. It's not surprising that Adam Sessler asked Gabe Newell the same thing about City 17's inspirations in his Leipzig interview on X-Play. Well documented though, GamesRadar. Love the site and the new comments feature.
you've got it all wrong, the game was built on pictures taken in Sofia, Bulgaria .Check it on the net if you want, and those pics are no were near to the real thing here in Sofia :)
Since City 17 was based on Eastern Europe and Leipzig is located in (formerly communist) East Germany, it's not surprising they look similar. Still, its a funny montage. Well done.
I would only every go there if i had a crowbar! Cos like theres only a gigantic strider, a hunter and a zombie. Now if there was a super-zombie then i'd be a bit screwed!
