just had a few ideas because i have loved the new weapons added in the past months and just thought id share some of my thougts
crossbow - range that lowers because of velcoty but not alot of recoil and piercing damage
cannonball, idk i just thought a weapon similar to one that be good against hull health
a twin missle launcher - shoots 2 missles at a slow rate
also it be nice to see new heavy weapons in the future
