SR-25 and the Silenced M9, indeed it's not a lot, not only does the sniper rifle cost in the region of $100k or more to create but also the ammo is very expensive and yet the gun isn't that good as it takes at least two or three body shots to kill. As for the M9... It's a pea shooter, unless you're shooting an AFK player you won't kill anybody with it. I was personally thinking about a one hit stabber like somekind of shiv which would degrade after a single use and would cost like $20k to make using at least five refined metals and a lot of glass shards etc however, it would really have to be balanced out so it doesn't become an instant mayor killer, although it would be cool as it would mean running up to the mayor or sneaking up very carefully. As for the machine guns, I wouldn't mind a silenced MAC-10. The idea of putting a silencer on almost every weapon is not the answer my friend. You must understand that 9 times out of 10 you don't see the muzzle flash when the gun is shot and it's quite silent however, it's not a one shot killer. My idea of a perfect silent weapon are throwing knives. Just like the ones in Metro 2033. Of course they'd have to be balanced out but in my opinion, having no crosshair is a big challenge already and if it would take one hit to the head and two to the torso I wouldn't mind them being added. What do you think?
