The Cursed Ammo serves as a prerequisite for unlocking the mastery reward, the Killshot operator skin, within the Horde Hunt event of Modern Warfare 3 Season 2.

Here’s everything you need to know about the Cursed Ammo MW3, including its effect in the game and how to unlock it.

What is Cursed Ammo MW3?

Cursed Ammo is the third and last reward in the Featured Zombies section of the Horde Hunt event, following the Tiny Screams charm and Dogs of Hell calling card.

This unique offering is the sole skin designed for the munitions box, a field upgrade that replenishes ammo and equipment for both you and your teammates.

Despite its cosmetic appeal, the Cursed Ammo MW3 does not introduce any gameplay effects to the munitions box functionality.

Nevertheless, obtaining it remains imperative for unlocking the coveted Killshot skin for Swagger, as it requires the acquisition of all three Featured Zombies rewards.
