Tips
- The last Silver Skull can be found in the Campaign level Covenant and in order to obtain it, you must go through the Halo rings at the end of the level in a certain order and you must kill all the Flood before doing so.
- The first ring is at the entrance of the level and the 7th ring is at the end by The Prophet of Truth.
- This is the order: 4 6 5 4 5 3 4 (has been confirmed)Be sure you are going through the right ring and that you get through it; it can be quite difficult and time-consuming, so try it in co-op if possible.
- After jumping through them in this sequence, you will be awarded the “I Would Have Been Your Daddy Skull”. It will be right next to the bridge that brings you over to the Prophet of Truth.
- For the IWHBYD skull remember to finish the level or you won't recieve it. That is the only skull you must finish the level for.
- Remember to always start from the beginning of a level when getting a skull or it won't be there.
- Remember, you must be on at least the Normal difficulty and you do not have to finish the level to get the skull, you just have to grab it.
Warnings
- Make sure to be playing on the Normal difficulty or higher when getting skulls
- You can get the IWHBYD skull at any time
- Remember to select mission start at the beginning of each level to get the skulls, they won't spawn if you start at rally point alpha or others.
