If you like this mod, be sure to check out my skin: http://videogamemods.com/justcause2/mods/Player/A-Blue-Rico/ 

So all I've done in this mod is make it so that you can dual wield assault rifles and added a couple things to them.  They shoot about 4 times faster, do 100% more damage and have unlimited ammo.  I did use the weapons.bin file so if there are any other mods you have installed with that file just view the readme.

Other than that, installation is pretty basic,

 Just put the file in your dropzone folder inside of Computer\Local Disk\Program Files (x86)\Steam\steamapps\common\Just Cause2

If you don't have one just make one in that directory

and play! 

 If you have any problems post them and I will try to update my mod! 

1.1: to differ from http://videogamemods.com/justcause2/mods/other/Gameplay/Agency-Super-Pack-V2.0/ I have made this mod WAY more powerful, how? thats for you to find out!

1.2 minor update: increased bullet velocity and bullets per shot 

1.3 added quad-rocket revolvers, THESE THINGS CAUSE FREAKING NUCLEAR EXPLOSIONS!!!!! Courtesy of C. O'Keefe

1.4 HUGE MEGA UPDATE OF HAPPY HAPPY JOY JOY TIMES! basically I mae every weapon you can pick up better... 

PS: the 1.0 folder is still in the file so if you don't want your assault rifles to have amazing powers, you can.
