How to Duplicate any item
This MUST be done in solo mode: When you reach a checkpoint during any campaign quest drop the item on the ground you wish to duplicate(Can be your all your items in your inventory). Then kill yourself by using deobombs or molotovs, When the respawn timer begins to countdown pause the game and reload your checkpoint. When you respawn all the weapons you dropped will be back in your inventory and they will also still be laying on the ground where you dropped them. Side note: you also do not suffer the cash penalty from dying since you reloaded the checkpoint.
