Battleheart

"Smash through the heart!"

- In-game description

Battleheart is a Rare Specialized Weapon Variant of the MK46 introduced as part of Love's Extinction in Call of Duty: Age of Extinction. Forged by Mr. Tachibana using a frame of the MK46, he improved upon the original weapon and created Battleheart as a Specialized Weapon Variant, and sold the weapon to his Armoury clientele during Valentine's Day 2027.

Like all Specialized Weapon Variants, Battleheart cannot be customized with additional attachments. Unlike the original MK46, Battleheart deals more damage to enemies due to its integrated AP/FMJ Rounds and has a lot more ammo with its Double Drum Mags along with having a Foregrip for increased recoil control and accuracy.

Weapon Perk
The Battleheart's Weapon Perk is "Vengeance" where dealing damage to enemies will increase the effectiveness and overall damage of the integrated AP/FMJ Rounds.

This Weapon Perk comes unlocked once obtaining Battleheart.

Trivia

 * The reason why the Battleheart's visual appearance is largely different than the MK46 was because Mr. Tachibana extremely disliked how the weapon looked, but still used it for its sturdy effectiveness.
