For example, the HUD will show '56/100 Grunts Killed' when you have killed 100 Grunts for that objective, the skull will appear. Also im having the same issue with Halo Wars : Definitive Edition, so fairly i'm confident its my account Im wondering if it'd be wise to just wait until the game is fully released to see if that helps.

This mod contains around 35-40 different troops that may be trained as well all sorts of custom Tech, including main base Tech. This mod for the UNSC only, and the Campaign.

To simplify this, the objective will have a counter that pops up every time you kill a unit of the designated unit type. All The Units is a more than massive mod for Halo Wars Lots of New Units, Tech, and a entire new way to build your main base as the UNSC. Set in the year 2531, before the initial Halo first-person shooter. Developed by Ensemble Studios, Halo Wars for Xbox 360 brings all the drama of a real-time strategy game to the popular Halo Universe. Once this objective has been completed, the skull location will flash on the mini-map for a few seconds, so it's important to watch the map as you complete the objective. Get your hands dirty in the early stages of the epic battle between UNSC and Covenant.

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.
