Alas, Poor Andrew Thomas

Alas, Poor Andrew Thomas is an achievement in Halo Wars that is unlocked when you receive your first skull. Its name is a reference to the famous line in Hamlet, "Alas, poor Yorick", which was also parodied in the Halo 3 multiplayer achievement Alas, Poor Yorick.

Tips
Just collect a single Skull in any of the missions. See Graverobber Achievement.
