Mods and hacks can be helpful interchangeably, but there is a slight difference. Mods are by the game developers to change or add to the game. They are official releases and usually part of an update or DLC. Hacks. Another difference: They change the game files to give players an advantage in online play or change the game’s appearance. While mods are by the developers, hacks are not and can get you banned from playing online.
