I’m pretty sure the developers at Blizzard liked Snowpiercer a lot, because one of the new dungeons in the upcoming expansion will be something similar. Most of the time we’ll be fighting on a huge, moving train of the Iron Horde.
Imagine the claustrophobia and last-man standing dystopia of Battlestar Galactica married to the comedic oppression of Terry Gilliam’s Brazil. Now imagine all of that is stuck on a train. That’s Snowpiercer.
