The Division must have had an entire team working on Easter eggs, given the quantity that have been discovered. The real challenge in game seems to be finding a few square meters of space that doesn't reference a TV show, game or film. Let's work through the list:
First up we have MR BEAN. Mr bloody Bean, as discovered VikingWarriorSkjald:
And, for reference:
There's also a couple of Teenage Mutant Ninja Turtles Easter eggs, as discovered by PeaceFrog89 and OniZombies:
I covered this Shaun Of The Dead Easter Egg in The Division separately, but it's worth including again:
While we're looking at echo-based Easter eggs, let's throw in this Breaking Bad one from synchromatik:
Ubi isn't above referencing its own games, such as this Splinter Cell nod from OniZombies again (as are the next few):
Along with Grow Home and Rabbids because why not?:
There's also a ton of homages to pop culture stuff like Sons of Anarchy:
The Martian from ntgoten:
Aaand, how about some Adventure Time? (Via OniZombies again):
And that's just a quick flick through the best. There are also references to Rick and Morty and Batman in the missing persons lists, a mannequin in the street that looks a lot like Fred from I Am Legend, and a possible Doctor Who one involving more mannequins. Let me know if you find any other good ones.
