With the latest expansion Aftermath, you can rest assure there is indeed another Dinosaur Easter egg hidden here as well. This was confirmed by Craig Mcleod from DICE who when asked about the egg told VG247:
I’ve seen that yeah. I think each game gets it’s kind of little…quirk that players like. We understand this and actually, we do have one hidden Easter Egg which is along this theme in Aftermath.
The theme of Dinosaurs running rampant on the battlefield has been teased a lot by the developers. The flames were fanned once again when the game’s community manager posted on reddit:
Glad to see the enthusiasm. Really, though, if this is something you guys want the best way to go about it is to try to get #BF3Dinos off the ground on Twitter. If that sh*t trends it’s pretty hard to ignore.
How awesome would a new expansion be where the battlefield has been turned into the island of Jurassic Park, with Dinosaurs running everywhere and players calling in the cavalry to gun them down with superior fire power.
Aftermath will be released for Battlefield on December 4 for the premium subscribers of Xbox 360. Non-premium members will get it on December 18.
