Breath Of The Wild 2: 7 Details You May Have Missed From The E3 2021 Trailer
5. Link Has A Flamethrower
This can't be overstated enough; Link has a freaking flamethrower!
The original The Legend of Zelda: Breath of the Wild had some cool weapons, including numerous swords, bows, magical rods, and even boomerangs but nothing close to a flamethrower.
Whether this heralds a variety of Sheikah themed guns is unlikely but possible. The Sheikah invented teleportation, the ability to freeze time, and giant robotic beasts - they could invent a handgun.
A flamethrower would hold more interesting gameplay in the dynamic world of the Breath of the Wild engine than a gun would though. Imagine setting the ground alight just to use the draft created to make an escape on your glider. You could melt ice, burn down trees, cook meat, among many other things.
We're more likely to get a variety of elemental guns than anything that shoots bullets. A freeze gun or an electricity gun would fit The Legend of Zelda: Breath of the Wild perfectly.
With so much utility though you can probably expect the flamethrower to either be really rare or have quite low durability. Nintendo isn't going to allow you to burn the world to the ground.
