The Lone Walkers is an endgame Bulletin Board quest where you get to hunt down zombies in Quarantine Zone: The Last Check.

The quest isn’t particularly difficult to achieve, especially since you’ll have your gun by this point. However, the exact location of the zombies can be the confusing part, as this quest is slightly glitchy. This quest will tell you all you need to know to complete the quest.

The Lone Walkers quest will be available on day 21 on the Bulletin Board. Interact with the notification when it pops up, and the quest will be automatically active. To complete the quest, you’ll have to kill three zombies.

If you don’t take care of the undead, they will increase the horde’s attraction. Let’s look at where you can find the zombies.

How to find the zombies to complete the Lone Walkers quest

Out of the three zombies you’ll need to eliminate, two of them will actually be outside your base. However, you’ll first need to take down the one that’s already within your outpost. You’ll find this creature in the Garage region.

Be careful when you enter, and carry your gun because you’ll have to defend yourself. The zombie should be there in the open, so shoot it in the head. The next zombies are outside your base. Go to the watchtowers that overlook the backside of your outpost.

Once you’ve cleared the Garage, go through the doors, and you’ll find the watchtowers. From there, you can take down the zombies outside the outpost. Kill two of them (there will be more), and you should have completed the objective without any trouble.

However, it can happen that a zombie doesn’t spawn in the Garage. In that case, you’ll want to restart the day and make another attempt. A note of caution: deactivate automated defense turrets if you have them bordering your Garage. Don’t try to shoot anyone outside your main entrance since they’re civilians. Killing them will not only reduce potential survivors but also cost you dearly.
