Where are all the skulls on Halo 3?

Answer 1

first skull i found was the grunt birthday party skull

REMEMBER DO NORMAL NOT EASY

grunt birthday party: location crows nest: when you get to the part in the sewer looking place with the flying bug looking things flying through the pipes go to the very edge and look down too see a arrow pointing back fall forward then fall backwards quickly then you should land on that platform turn around and walk forward to see the skull

another skull: location : crows nest:as soon as you start the mission head forward don't go down the stairs and go up the stairs and keep going past the way down once up the last stairs turn around and look for a little ledge jump to it then jump on the steel line then turn to right and jump up on pipe then walk along pipe skulls on edge
