Own Worst Enemy
Own Worst Enemy is an Achievement in Halo Wars that is unlocked when the player receives a gold medal with all Debuff skulls activated.
It is worth 20 Gamerpoints.[1]
Tips
The Debuff skulls are: Fog, Sickness, Rebel Sympathiser, Rebel Supporter and Rebel Leader.
One of the easiest ways to unlock the achievement is to play Repairs on Easy difficulty. Activate the Debuff skulls at the beginning of the mission.
Send your Spartans and an Air Unit to the center area. Spend all your time and resources on Cyclops units and Turrets.
Prioritize the Cyclops units. The more you have working on repairs, the faster the level will end.
Another easy way is to play the first level on easy and work quickly. The low resistance and large time bonus helps.
