In the add-on "Live Freemium or Die", before you fight the final boss he says, "You think microtransactions are your ally. But you merely adopted the freemium. I was born in it. Molded by it." This is a reference to the character 'Bane' in the movie The Dark Knight Rises.

On one of the gravestones in "Live Freemium or Die" reads:

"Here Lies:

Villager Jon
(???-2013)

Killed by the Creatures. Real Talk? He Wasn't Paying Attention."

This is a reference to the online show "Game Grumps" and its host Jon Jafari "JonTron".
