There are no skulls in Halo Reach.
Skulls
Find them your self
You click on the tab that says skulls and you click on the skull.
The skulls are hidden all over the map. To get them all you have to do is find them and pick them up.
There are various skulls you can find hidden in Halo: Combat Evolved. The first skull is hidden in the first room in the game behind some barrels.

no.... im a holo freak.... in fact to get skulls in halo you find them when you play each level... so each level has a skull hidden in it... you just have to look for it...
You can, just like in Halo 3. It will have more skulls in it too. I'm not 100% sure what all of the names are and their functions, But I will test it VERY soon.
