We don't have cheats on this website.
This article was written to clarify what is it and what it's not and if there are cheats for this game.
What is a cheat?
This is nowadays a code which you can enter to gain advantages in a video game. It's not a program which you can download, it should be already in the game implemented. Although you gain some advantages, cheats are official and legal because they were implemented by the programers of the game.
The most games don't allow them in the multiplayer only in single player.
Don't confuse cheats with hacks, mods or bots.
