Big Bertha is my way to improve the most expensive, crappiest weapon in history of Counter Strike.
It's a M249 that shoots at 50% starting rate of fire, and every bullet you fire increases it by 2%, up to 200%. It has 150 total ammo and no reserve ammo, with the cool ability to replenish 2 ammo every 0.5 seconds. Everything is configurable.
If M249 doesn't get a rate of fire boost, in its peak, it will shoot 1500 bullets per minute, or 25 bullets per second, faster than any weapon in CS:GO
Big Bertha works the funniest with these attributes on the weapon_m249, which mimic the negev's recoil:
"recoil angle" "0"
"recoil angle variance" "0"
"recoil magnitude" "30"
"recoil magnitude variance" "2"
"recoil seed" "57966"
To add the recoil stats, search in folder "csgo/scripts/items/items_game.txt" an entry of "weapon_m249_prefab" and append in the end of attributes entry the code above.
If you're too lazy to edit the recoil, it'll be extra hard to control a 200% fire rate gun.
I don't expect any server to use it but someone might surprise me.
