Egg-stra XP! Is another Achievement related to Call of Duty: Ghosts – Onslaught DLC. It’s worth 20 Gamerscore and requires you to:
Complete the Egg-Stra XP challenge and then destroy a hive in the Onslaught DLC package.
Basically, this requires you to enter the Public Matches and shoot all four hive locations in the four multiplayer map packs.
You don’t necessarily have to shoot all of them during a single match. Once you destroy a hive, your progress will be saved, and the rest can be completed any time after that.
The first hive is located in the Ignition map, and you will find it near the very center of it. You will come across a container that will lead you straight into the underground alleyway. Once you get there, the hive will be in plain sight.
This one is also located at the very center of the map. Once you get to the center, get to the Cave System (Light Blue on your mini-map) followed by heading to the Waterfall (Black spot inside the Light-Blue area). Aim at the top of this Waterfall and you will end up destroying the hive.
You will need a gun with a decent long range to get this one. While in the Bayview, head to the Lighthouse and keep on following the walkway to your left. Have an eye to your left and shoot the hive just beneath the pier. A Thermal Sight will help you better identify the hive.
Head to the gas station with a round signboard and jump onto the green container; right in front of it. You will need to aim at the closed street; right next to the green building (with Transmission written on it) to shoot down the final hive.
Once you have destroyed all these hives, you will need to jump into the Nightfall and destroy a hive there to make the Achievement pop-up!
