Buy Station Locations

The only way to get Sentry Guns in Zombies mode is to purchase them at the Buy Stations in Threat Zone Level 2 and Level 3 for 2,000 Essence each. There are many Buy Stations in this area, so you’ll never have to look out for them for too long. I marked most of the Buy Stations on the map below with red dots.

Sentry Guns are prone to breaking, so you’ll definitely need to buy more than one. Be sure to acquire lots of Essence by killing zombies and completing contracts.

Best Spots to Place Sentries

It’s best to transport Sentry Guns in vehicles and place them at specific locations on the ground where they’ll help you effectively deal with enemies, including:

  • Defend Ground Stations
  • Aether Extractor Contracts
  • Mercenaries Contracts
  • Mercenary Strongholds
  • Exfils

The last one is especially important, as you’ll need all the support when the zombies start swarming around you while you’re waiting for the Exfil helicopter to arrive. It’ll take you about 30 seconds to step onto the helicopter, and you’ll surely be distracted doing that instead of aiming and shooting. That’s where Sentry Guns can be really helpful at dealing with the zombies trying to prevent you from escaping.

That’s all you need to know on how to get Sentry Guns in Call of Duty: Modern Warfare 3. Stay tuned for more CoD MW3 tips and tricks articles, such as how to find and destroy mercenary convoys and find out whether you play Zombies in split screen.
