Zombies Unlimited Sentry Gun Glitch

Buy a Sentry Gun from a Buy Station

To do the this glitch, you'll first need to buy a Sentry Gun. The Sentry Gun can only be bought from a Buy Station in a Medium Threat Zone and costs 2000 Essence.

Kills with the Sentry Gun count towards weapon level progression XP, as long as you have the desired weapon equipped in Zombies.

How to Farm Essence

Stack Sentry Guns at an Exfil Site

Once you have a Sentry Gun, proceed to an Exfil Site. Take our your Sentry Gun and prepare to make some dupes, you'll need to have some quick fingers for this.

While your character is in the middle of the animation of deploying the Sentry Gun, quickly drop the Sentry Gun. If you did this correctly, you should have a deployed Sentry Gun and another unused one on the ground.

How to Exfil

Only Deploy 2 to 3 Sentry Guns at Once

We recommend having only 2 to 3 Sentry Guns deployed at once. Having too much will slow the game down for everyone, or even crash the game! This runs the risk of getting reported and eventually banned, so it's not worth abusing.

Call for an Exfil

After you've set up your Sentry Guns, call for an Exfil and let the Sentry Guns do most of the work. Eventually the Sentry Guns will expire so you'll have to keep placing them down.

You can call for multiple Exfils for multiple waves of zombies.

Best Items to Exfil

Equip Preferred Gun for Weapon XP

While you let the Sentry Guns do the work for you, equip a weapon that you wish to get weapon XP on. Doing this will let you hit two birds with one stone!

Farming Preparation

To start the best way of farming XP in Zombies Mode, there are a few things you might want to do:

1. Pick a weapon you want to get weapon XP on.
2. Select the Energy Mine for your Field Upgrade slot .
3. Use XP Tokens if available for efficiency.
4. Turn off squad fill to avoid interruptions from random teammates.

Once you've done these, you should be all set to start a match.

Find an Exfil Site Low Threat Zone

Exfil Map Icon

Once you're in a match, you'll need to wait for at least 2 minutes for Exfil Sites to appear on the map. When they appear, head towards those that are on the outskirts of the map, or on the Low Threat Zone.

Call for an Exfil and Kill Zombies with Energy Mine

When you're at an Exfil Site, call for an Exfil then just keep killing zombies. When your Energy Mine field upgrade is charged, use it on hoards of Zombies. Energy Mines will count towards your weapon level progression, even if you didn't fire your weapon, so it's a good way to farm Weapon XP for weapons you can't quickly level up (like Sniper Rifles, Marksman Rifles, and Melee).

Do not board the Exfil Helicopter and let it depart without you. Roam around the vicinity and wait for about a minute until the Exfil becomes available again to summon another wave of zombies. Keep repeating this for massive injections of XP.

How to Level Up Fast

Dealing with Growing Hordes of Zombies

After a significant amount of time has passed throught the match, even more zombies will spawn. You can try to find a Pack-a-Punch in the area and use it on your weapons, if it gets hard to deal with the exfil site zombies by yourself.

How to Pack-a-Punch Weapons

Exfil Before Timer Runs Out

Below your minimap is a timer that continuously ticks down. As it runs out, the enemies will become tougher and an Aether Storm will engulf the Exfil Sites when 15 minutes remain.

Make sure to Exfil before the Aether Storm to get the maximum amount of XP!
