can someone explain this pineapple?
One side of a Junker has double carro, the front mount is also carro. The right side is usually meta.
Right side is never meta for a true Pineapple build. Left and front guns are carro, right side is dual Hades. Original 'I have a Pineapple' had dual mortars, but upgraded to the Hades. Other variants are dual mines or mercs. Never a Gatling. Pilot tools vary a little, but are generally Moonshine, Impact bumpers, Claw, and Buff.
The method of flying is a secret only divulged to those on the ship.
