The Sentry Gun will be your line of defense and act as a supportive tank in Modern Warfare 3‘s Zombies mode. Whether you are playing with friends or risking it all solo, this mounted weapon can literally save you from the brink of death as it protects you in battle.
This is the best way to get a Sentry Gun in MW3 Zombies.
How to get a Sentry Gun in MW3 Zombies
The fastest way to get a Sentry Gun in MW3 is to purchase one at one of the many Buy Stations inside of the medium or high threat level areas. This means you will not find Sentry Guns in the starting zone—you’ll need to move inward to purchase one.
Each Sentry Gun will cost you 2,000 Essence. You can acquire 2,000 Essence quite early on in your deployment, but we recommend using a Pack-a-Punch upgraded weapon, alongside having an abundance of ammo and armor plates, before moving in and grabbing a Sentry.
You can also obtain Sentry Guns in random loot caches or as rewards for contracts; however, these require a bit of luck. Buy Stations are the way to go for a quick and guaranteed Sentry Gun.
It’s even possible to find a Sentry Gun in a Mystery Box, but you’ll need to be lucky! The Mystery Boxes are marked by a bright blue beam shooting into the sky, or on your Tactical Map as a box with a question mark. Otherwise, look for the dollar symbol on your map for a Buy Station.
The Sentry Gun is needed for specific missions in MWZ like Act One’s tier five mission Hands Off. While this version of a field upgrade isn’t readily available off spawn to pick up out of supply crates, there is a simple way to get one.
A Sentry Gun is incredibly handy against massive hordes of zombies or dealing with convoys and small military campsites. As the Deadbolt Turret isn’t always in an advantageous spot to mow down the enemies in Urzikstan, the Sentry Gun is a must-have for solo MW3 Zombies players facing the red zone alone.
How to use a Sentry Gun in MW3 Zombies
To use the Sentry Gun, press the key or button attached to your killstreak in MW3. The Sentry Gun icon will be visible on the right of the screen with the key or button highlighted beneath it. Simply press it, then line up the mark on the ground where you want your Sentry Gun to face.
If a horde of zombies comes at you from another angle, make sure to head back to the Sentry Gun and rotate it to face the enemy. Press the interact button once you are behind the Sentry to pick it up, then turn and place it back down. Of course, this means you will have to carry this around everywhere so make sure you are near any mission objectives if you decide to place it down.
The Hands Off mission requires you to get 20 Sentry Gun kills, which I completed by mounting the Sentry Gun on the back of a cargo truck and driving merrily around the map as the Sentry Gun mowed down any and all zombies in my path.
