I’m not sure if people are interested in this one that I found,
but I thought it could be worth sharing for those who like hunting Eastereggs:
An easteregg can be found in the mission “Hogging Supplies”.
The item of this quest is hidden in what is called “Snowball’s pen”.
Snowball is a character (one of the piggs) from a book called “Animal Farm”
by George Orwell (1945).
A book truly worth reading if I may say so.
It’s about an animal rebellion against humans on a farm.
The book is quite political but can also be read just as a simple story.
One of the best quotes in the book IMO is:
"All animals are equal."
Which later on in the book unfortunatelly evolves into another quote:
Al animals are equal, but some are more equal.
I changed/translated this second quote for myself to something new:
"Al animals are equal, but unfortunatelly some think they are more equal."
Anyway, Snowball’s pen, that"s an easteregg right there
