Turn every headshot into an explosion with the Grunt Birthday Party skull.
You will find this skull on The Arbiter level. When you reach the mission objective “Pursue the heretic leader,” you will know that you are close to the skull. Once activated, the skull will cause the text “Grunt Birthday Party” to appear on your screen.
