How To Get The Small Net Gun And Hush Dart Tranquilizer Gun

There are two types of weapons that will serve your purpose,Net GunsandTranquilizer Guns. The first is available from Chapter One, while the latter is only available from Chapter Two onwards, starting with the Hush Dart.

From Weapon Chests

There are a couple of ways to ensure you have the correct weapon with you when you’re exploring the Giant Blue Hole, though they’re related to one another. First, you’re going to have tofind one in a weapon chest— the silver chests with gold gun icons on them, as shown in the image below.

It might take quite a bit of searching before you find a chest with a Net Gun or Hush Dart inside. Once you have a weapon from a chest, it will remain with you while diving for this session unless you choose to swap it out for another weapon you pick up.

From Duff’s Weapon Shop

To get a permanent Net Gun or Hush Dart Gun,you need to find three blueprints of those specific weapons— this means you need to find and pick up that type of weapon three times from Weapon Chests — and then you can purchase one from Duff’s Weapon Shop, providing you have the right crafting materials.

For a Net Gun, you’ll need:

For a Hush Dart, you’ll need:

Once you have a weapon,be sure to equip itbefore you dive so you may enter the diving session with the right weapon and not worry about having to hunt one down in a Weapon Chest.

How To Catch Jellyfish

Once you have the right weapon, you’re able to track down your jellies and get ready to capture them.

You simply need to aim as you would with any gun and fire at the jellyfish.

For the Net Gun, it’ll get caught in a net, and you’re able to swim over and collect it with the press of a button. For the Hush Dart, it’ll take a few seconds for the tranquilizer to take effect and then you can swim over and collect it.

If you run out of ammo, you can replenish it by collecting one of the ammo consumables — the small cans with the gold bullet icons on them — as shown below.
