Army of Two: The Devil's Cartel came with a Pre-Order DLC called the Overkill Edition.
This came with a wealth of content.

The Dia de los Muertos facemasks and tattoos were designed by tattoo artist Paul Booth and graphic designer Steve Soto. Booth designed the "Dia de los Muertos" and "Skull Inception" facemasks and the "Last Rites" #1 to #4 tattoo sets. Soto designed the "Aztec Warrior" and "Black Widow-Maker" facemasks and the "Mayan" and "Native" tattoo sets.
