Skull/Halo Wars

Skulls are objects that Ensemble Studios hid in levels in Halo Wars. They are meant to make gameplay more challenging and interesting.

How to Find Them
Each level in Halo Wars has an optional objective where you are asked to kill a certain number of a certain unit type, such as killing 100 Grunts in the first mission, Alpha Base. Once this objective has been completed, the skull location will flash on the mini-maps for a couple of seconds, so it's important to watch the map as you complete the objective. To simplify this, the objective will have a counter that pops up every time you kill a unit of the designated unit type. For example, the HUD will show "56/100 Grunts Killed", when you have killed 56 Grunts for that objective the skull will appear.

The skull will not appear in its location until the objective requirements have been met.

You can press right on the D-pad after you have completed the objective and it allows you to see where its located.
