So I know that people have seen the elevator Easter egg, as well as the Easter egg Easter egg. (google them if you have no clue what I'm talking about...)
Here are some things that I've seen in my game play
1. The first one is trivial as far as an "Easter egg", hence why I didn't say that in the title. This is more of a "wait... what?" moment, and is easy to find. Go to an ammo box, any ammo box, and look what size ammunition the shotguns in Crysis 2 utilize.
For those of you that don't know, that's kinda weak to be using against Ceph and CELL in my opinion.
2. This one can be called an Easter Egg, and it actually references an egg from Crysis 1, shown here:
Remember our old friend Badowski, Crytek did...
So there you have it!
