The Last Stand: Aftermath: How to Craft a Suppressor
The Final Stand: Aftermath focuses on picking your battles, and not being overrun by zombies. You should reduce the sound from your firearms by using a suppressor as soon you can.
You will need 1x plastic bottle and 1x tape to make a barrel attachment. These items can be found all over the map. It can be made quickly by pressing the d-pad on the controller.
Once the item is crafted, go into your inventory to select attachments. To make your shots more quiet, attach the Bottle Supressor to your chosen ranged weapon. Keep in mind, however, that they don’t work silently and there might be better suppressors available.
