How about you can have a double barrel shot gun or 2 sawed offs and the sawed off you can put on your back.
Double barrel: 9 damage, low freeze, about $45k
2 Sawed off: 9 damage, medium freeze, maybe about $60k?
Saber throw(attament): maybe 20 ec
Golden Tommy: 10 damage, freeze(m4), 500 ec
Idk lol just ideas i just think would be nice and if these things could happen, np with price changing
