Battlefield 4 USAS-12 Pack on Develop013's animations.
This will feature the USAS-12 shotgun complete with all the American combat optics i.e.: Reflex RDS, Eotech Holo, ACOG 4x Scope, & the M145 3.4x. this Pack will hold a total of 5 guns (all of the different variants of this gun are all in the "bf4_usas12" folder). *IMPORTANT reminders: check out the "INSTALLATION.txt" before installing this addon. this should work just fine with the vanilla Singleplayer version of BF2 and 1.5 patch. If u have any questions feel free to leave ur comments down below ~ Have a good one and Enjoy :D
