I would like to see some of these weapons (although some of them might already exist)
A flash bomb(use about 3 times)
A parasite(attaches to the player and sucks them dry of life slowly)(one time use)
An aerial bomb(when dropped from something like a plane, goes straight down. Very fun for war DMs >:D)(endless use)
A Boomerang(endless use)
round-about sword(flies around the player once, destroying any enemies at ground level.)(endless use, but you can't move while using it.)
Bullet grenade(shoots several bullets out in multiple directions, could also be known as debris, instead of bullets.)(one time use)
