During the MW4 DMZ Mission: Operation Shopping Hacks, you will be required to power the Lab Door with Robot Cores. However, you might already have a few Destroyed K9 Battery Cores, but these aren't what you need. You need the perfect-condition ones, which are obtained before the robot dog is destroyed. Below, we'll share exactly what you need to do to finish this objective before a hostile team comes and wipes you out.

Here's how many players you can encounter in DMZ, along with the total squad size you need to know about if you intend to jump in as a solo player.

When you're inside the NuriGO Mall, you will find a station with robot K9 units, which spawns these explosive robot dogs every few seconds. You need to kill the robot dog and grab the dropped K9 Battery Core before it explodes, because when the robot dog explodes, the item becomes the Destroyed K9 Battery Core.

The easiest way to do this is simply by shooting the K9 in the head or in the glowing spots on its back, and as soon as it's deactivated, snatch the core and run, as it will explode after a few seconds. Once you have 4 Battery Cores, return to the Lab Door and place the cores inside to open them and find your next objective inside.

Feel free to drop any K9 Battery Cores you have after you have opened the doors, as they are only worth 200 DMZ Cash each, so it might not be worth returning them to the FOB when you can get other valuable loot.
