It's a simple script that spawn your favorite weapons with just one key. 

Bonus: in addition to the weapon, there will be an AI voice of CJ by Ariana Grande (yes you're not dreaming haha).

Every time a weapon is activated or deactivated, you will hear Ariana Grande's voice imitating CJ's words.

To activate or deactivate the weapons select their corresponding keys as follows:

List of commands:

UZI: U

M4:K

RPG: J

FLAMETHROWER: L

MINIGUN: O

SHOTGUN: I

SNIPER: P

MP5: M

I advise you to load a saved game rather than starting a new game. 
The script does not work well on a new game.

Good game!
