On the Citadel, the player can interract with a vending machine that dispenses a popular soft drink named Tupari. When interracted with, the machine will play a number of slogans promoting Tupari, one of which is "Tupari brings your ancestors back from the grave!"

You're in the Pepsi Generation!" was supposedly misinterpreted in Chinese (or other Asian languages) as "Pepsi brings your ancestors back from the grave."
