In How to Fish, the Dazed Games co-op shooter-fishing game on Steam, weapon attachments fill four weapon slots: extended mag, laser sight, an optic, and a muzzle attachment.
Despite the name, How to Fish by Dazed Games on Steam is a shooter as much as a fishing game, and attachments are how you turn a basic gun into something that can carry you through the late islands. They are weapon upgrades, not fishing gear. When every one of a weapon’s slots is filled, that weapon counts as fully kitted — which is the whole basis of the Fully equipped achievement.
The four weapon slots and their options
| Slot | Options |
|---|---|
| Extended mag | Extended mag |
| Laser sight | Laser sight |
| Optic | Red dot, or sniper scope |
| Muzzle | Compensator, or suppressor |
Key Every weapon has the same four slots. The extended mag and laser sight are one-choice slots, but the last two are either/or: the red dot and the sniper scope compete for the same optic slot, and the compensator and suppressor compete for the same muzzle slot. You pick one from each pair — you never run both at once — so “fully kitted” means one attachment in each of the four slots, not owning every variant.

When full attachment setups become available
Full slot coverage on a weapon is possible earlier than you might expect — a completely equipped gun is technically doable from Island 3. What changes later is the size of the pool: Island 4 adds the sniper scope and the suppressor as options, so that is the point where every slot has its full set of choices.
Practically, though, most players hold off until the Volcano (Island 5). Fish are worth far more there, so the money for a complete setup comes together much faster, making it cheaper to kit out on the volcano than to scrape the parts together on an earlier island.

Which weapon to fully kit
For most players the answer is the assault rifle. You want a fully kitted AR for the final boss regardless, so building one is effort you were going to spend anyway — and it drops the Fully equipped achievement right into your lap as you go. For the assault rifle specifically, the laser sight and suppressor pairing gives excellent hip-fire DPS.
A maxed Uzi or a sniper rifle can carry individual fights, and either is a fine weapon to lean on along the way. But if you are choosing one gun to pour attachments into, the final-boss prep points squarely at the assault rifle.
Kit out the assault rifle you’re already taking into the final boss — filling all four of its slots unlocks Fully equipped on the way, with no separate grind.

Frequently Asked Questions
Do you need every attachment variant for Fully equipped?
No. The achievement checks that a single weapon has one attachment in each of its four slots, so you only need one optic and one muzzle attachment, not both variants of each. Buying the red dot and the sniper scope, or the compensator and the suppressor, does nothing extra for the unlock.
Is it better to use the compensator or the suppressor?
For the assault rifle you plan to bring to the final boss, the suppressor is the stronger pick — combined with the laser sight it gives strong hip-fire damage output. The compensator, which tames recoil, is more useful earlier while you’re leaning on an upgraded pistol.
Should you buy attachments before the Volcano island?
You can, but there’s rarely a reason to rush. A full setup is buildable from Island 3 and the pool is complete from Island 4, yet the gun you actually want maxed — the assault rifle — usually comes together on the Volcano, where fish sell high enough to fund the whole kit quickly. Spending on attachments for a weapon you’ll replace beforehand is mostly wasted money.
