Guys, guys, guys!
Okay, get ready to have your mind blown. This is the best idea since boarding.
We have... wait for it... A MAGNET LAUNCHER.
Hear me out.
It fires a super powerful magnet attached to a balloon. The magnet exerts a spherical force towards itself within a 500m radius. The force decreases radially from the center point. It does nothing to ships, but bullets...
It bends bullets. Like how planets and suns bend light. Don't have a Merc arc? Fire off a magnet, then bend those shots around it, gravity slingshot style! Gunners missing shots? Jump off the helm and fire a magnet at the enemy ship! Enemy close to your mines, but expertly dodging them? Shoot a magnet at him, and watch his face as the mines move to him!
Combine with the new "Sticky" ammo to attach magnet to the enemy hull and watch every shot home in!
Batteries not included.
(Magnets, how do they work?)
