Grizzco weapons are unusual main weapons with varying properties. They are only available in rotations with question marks.
Grizzco Blaster
Grizzco Blaster can fire shots as quickly as the .52 Gal while retaining Blaster properties. As such, the weapon is very good on Rush waves and has excellent mobility.
Enemies behind the player can be hit by directly shooting at the ground; this reduces damage output, however.
(Editor's note: Fun fact: the blast radius is large enough to hit both the weak part of Grillers and the Smallfries spawning from them at the same time, so use that to your advantage!)
Grizzco Charger
Grizzco Charger is a Charger with long-range, instant-charging and piercing shots. As such, the weapon is very mobile and reliable in many situations.
The weapon is a prime candidate for killing Chinooks on Mothership waves and is able to kill most bosses without the need for Splat Bombs, even Maws.
Fish Sticks can be more difficult to kill with this weapon, although not impossible.
Grizzco Slosher
This Slosher has the ability to pierce through armoured bosses, including Slammin’ Lids, and has slow shots. Due to the slow velocity of each shot, it is easy to kill multiple enemies at once, including Fish Sticks.
Due to its ability to pierce, and despite the high ink cost of each shot, Grizzco Slosher players should relocate and line up their shots with multiple enemies, and trail their shots to move around.
The weapon is very good at dealing with armoured bosses and can effectively ignore enemy cycles for Drizzlers and Flyfish. It is also able to kill Mudmouths quickly.
The weapon is likely to struggle at killing Chinooks on Mothership waves.
Grizzco Brella
Grizzco Brella is a Brella without a shield. It has a high strafing speed and fires shots as quickly as the .96 Gal, making it a very mobile weapon. It is able to paint quickly, providing support for other weapons and against Flipper-Floppers.
To kill Steelheads effectively, it is recommended to jump and start shooting right before the Steelhead bomb appears to maximise damage.
Grizzco Stringer
This Stringer fires 9 arrows, dealing 1350 damage if all arrows connect after a full charge.
The weapon has good range, and can reach Chinooks high into the air if jumping before shooting at full charge. Similarly, this can be used to kill Fish Sticks from below, or before they start drilling their pillars.
Steelheads can be killed by lining up the two closest crosshairs with the Steelhead bomb.
Big Shots, Maws and Flipper-Floppers can be killed by lining up all crosshairs, requiring the player to be very close to their target.
The weapon may struggle if the player overextends in situations with many Lesser Salmonids due to the high ink cost of each shot.
