Spec Ops: The Line

To obtain this achievement, there are two ways:

• Chapter 1: At the beginning before rappling down from the bridge there are few Oryx on your sight so shoot one of them.
• Chapter 11: At the beginning you must save one bullet on your .44 Magnum so you can shoot the Oryx, otherwise if you let it run away it won't come back so reload until you shoot it.
