Hey there,
I remember reading somewhere, that people were searching for ideas for utitliy weapons, to increase the diversity of usable weapons.
I hope I'm not repeating an often posted suggestion here, but how about this:
A weapon that builds up air pressure and upon release it pushes your ship in the opposite direction you are facing. How strong the push is depends on charging time and ship mass.
So, how could this be used? Depending on the position of the weapon and the direction it is facing you could use it for quick evasive movements (i.e. dodge a charging pyra by quickly moving sideways), use it as a emergency break by facing forward in the direction the ship is moving. Or just use it for short bursts of speed by firing backwards. Maybe even let it affect other ships that are near you, so you can push them away.
What do you guys think?
Imo this could open up some pretty interesting trick-play and new strategies. One other plus would be, that this weapon is even then viable, when it is not facing the enemy (or rather: it's especially viable then), which means that you can utilize more of your ships weapon slots at once.
