Another new addition to Halo 3 are the Halo 3 skulls. These skulls once obtained can allow the gamer to change their game play by making it more challenging, or changing things such as dialogue or appearance. These skulls are generally placed out of the way so that gamers have to look around in different levels to be able to find them. This however does tend to lead to frustration for many gamers who have no idea where to look. For those gamers, there are many different walkthroughs available for them all over the internet to help them obtain these skulls.

All together there are 13 skulls that can be found, but there are two different categories of skulls. You have your Gold Skulls, which in general can change game play and allow the gamer to make it more challenging. There are 9 gold skulls in total and when a gold skull is first found, the gamer will receive 10 gamer points. If the gamer is able to collect all 9 skulls, then he or she will have unlocked the body and shoulder Hayabusa armor pieces.

The next categories of skulls are the Silver skulls. There are 4 of these in total. However when a gamer finds a Silver skull, they will not be rewarded with gamer points, but they do unlock achievements for the gamer. These skulls will change game play by changing things such as appearance, dialogue and the physics of the game. An example of this would be acquiring the famous IWHBYD skull. When the gamer has obtained this skull and puts it to use, then the gamer will hear AI Brutes saying things such as ‘Pie is good’ or they will hear the AI Marines yelling out ‘THIS IS SPARTA! ‘

In order for a gamer to obtain any of the Halo 3 skulls, they have to begin their level from the beginning and be playing on Normal difficulty or higher. Once a Halo 3 Skull has been obtained the gamer can then save and quit the level, they don’t actually have to finish it. This however is not the case with the IWHBYD skulls.
