Quote from Senturaone thing about columbia isn't believable: at the height of where the city supposedly is situated, (est. 20k-30k ft), temperatures are on any given day around -50 degrees celsius/ -58 F. People walking around in their summer clothes or being at the beach would be extremely unlikely unless they wanted to contract instant pneumonia and die within a few hours/days. there's a point where a dude remarks that it is set in july. fun fact: at those altitudes, seasons don't matter as temperature isn't going to drop below -40 degrees either how. It is also mentioned that columbia swerves all over the world, hypothetically the temperature could easily get below -100 degrees celsius/-148 F. for as much as other things are explained in the game, nothing is offered on how people survive this.
I don't know enough to say.
