Dave The Diver: How to Upgrade Weapons (2 Methods)

You can use something other than a fishing rod to get fish for your sushi bar in Dave the Diver. Instead, you’ll dive underwater and kill fish with different kinds of weapons. You start the game with a Harpoon, and you’ll eventually be able to use other weapons.

The only problem is that some aquatic animals are hard to kill because you need stronger weapons. In Dave the Diver, we’ll show you how to upgrade your weapons.

It won’t take long to open Duff’s Weapon Shop when you play Dave the Diver. Dave’s phone will show a message from Duff telling him to get his app. All the weapons you find under the water will show up here. He’ll give you a gun for free at first. Most of the guns you can get require you to dive while opening Weapon Enhancement Kits.

I saw these yellow boxes with a gun icon in some parts of Blue Hole. When you open one, you’ll find a random weapon inside. While diving, I sometimes got a temporary upgrade for my melee weapon or Harpoon Tip.

To obtain permanent upgrades, continue opening boxes until you acquire blueprints for new weapons. In your Weapon Shop app, you can see how close you are to being able to buy a better weapon permanently. To make one, Duff needs to find crafting materials in the ocean.
