Make backups of your original files before replacing!!!!!!!!!!!!!!

While using Open IV replace files:


"WEAPONS"goes in GTAIV\pc\audio\Sfx\resident.rpf\RESIDENT 
  
Health and Armor pickups are replaced in GTAIV\pc\data\maps\props\lev_des\minigame.img\ 	Models and textures for health pickup and body armor

"WeaponInfo.xml" goes in \GTAIV\common\data

All Weapon PROPS go in GTAIV\pc\data\maps\props\residential\details.img\			these are the models shown when you buy weapons from Lil Jacobs trunk

All guns/weapons models are replaced in GTAIV\pc\models\cdimages\weapons.img\

Cutscene Weapons are replaced in GTAIV\pc\anim\cutsprops.img\					weapons shown in cutscenes

Animations are replaced in in GTAIV\pc\anim\anim.img\						animation with more recoil for desert eagle , m4 and ak have fire delay removed


Check the description section of the mod page every so often because I do update the pack when I feel an improvement can be made

the best and most stable version of this game I reccommend using is "Grand Theft Auto IV - Complete Edition by  xatab"
