4. Rabid Animals
With the addition of animals to the game for the first time ever in the series, there is plenty of scope to subject the oft-docile creatures to chat codes. We know that there are going to be a variety of animals in GTA V, from dogs and deer to sharks and mountain lions, and while the latter are always going to be baying for blood, we thought it might be fun if all animals in the game wanted you dead. A "rabid animals" cheat certainly would be interesting, where deer suddenly see a flash of red and decide they don't want to be hunted anymore. This would make for an unpredictable gaming experience and we can only hope a code such as this exists. Conversely, it would also be cool if we could change shark behaviour so that they are no longer hostile to the player.
