Help me with skull location!

Well...what is the difficulty your playing on?It has to be normal to get the skulls.Try that and see if it works.

It doesn't have to be on normal, that just helps though. What you have to do is start the level from the beginning not from a checkpoint and and when you get to the part with the wraiths DO NOT destroy them if you do the skull will disappear.

You MUST play on Normal++ meaning Heroic or Legendary. You also ~MUST NOT~ destroy the wraith dropped by the phantom, the standard blue issued default wraith, you can destroy the anti-air wraith and the ghosts around you, I'd make sure any allies are dead since they target the wraith right away. :

Ps2man was completely wrong there are some skulls where you must start from the begining but if you read the achievment info "find and claim this skull on normal hard or legendary" and yes you can destroy the aa wraith but not the regular wraith.

You have to be on Normal, Heroic or Legendary.

Difficulty has to be Normal, Heroic, and/or legendary.

Nydla is right, destoy every thing exept the regular, droped wraith. Ps, start from beginig in normal,heroik,or legendary.

Be on normal.

Be on Normal or above, cannot die or restart check point.
