DEVESTATION EGG-STRA XP HUNT ACHIEVEMENT
This video will guide you to all 4 eggs and the hive needed for the achievement on the Devastation map pack.
There's one egg on each new map:
Under the meteor in "Unearthed"
On the bridge in "Collision"
On the supports in "Behemoth"
Under the roof of the shrine in "Ruins"
Eggs can be found in any order and you only need to shoot them one time. Once all eggs have been found online you'll earn 2000 bonus xp, play "Mayday" and destroy the first hive for the extra Extinction experience and achievement.
Special thanks to WRX Nation for the help!
