For this achievement you must shoot all 4 hive locations located in the 4 new multiplayer maps that are a part of the Onslaught DLC. You can quit the game once you shoot the hive and the notice pops up. These MUST
be done in public matches.
] - Ignition
This hive is located underground near the middle of the map. You have to find the container that leads into a small underground hallway. In this hallway, you'll find a hive on the wall.
] - Fog
Use the in-game mini-map for this. First, you'll want to make your way to the middle of the map, inside the cave system marked light blue on the mini-map. Inside the cave system, there will be a waterfall, marked by a dark blue circle on your map. Go up to the waterfall, aim inside to find the hive.
] - Bayview
Make your way to the side of the map with the lighthouse. Looking at the lighthouse, follow the boardwalk to the left, and aim off the side to find the hive under the pier across the water. You may need a long distance weapon for this hive.
] - Containment
On one side of the long street that runs through the entire map, you will find a gas station that is identified with a large circular sign. Jump onto the green dumpster in front of the gas station, aim across the street and to the left. You will find the hive on the roof of the small building next to the large green building.
After completing all 4 of these hives, you will need to go into an extinction game of Nightfall
and then destroy a hive using the drill to unlock the achievement.
