(THIS ACHIEVEMENT IS NOT APPLICABLE IN SPLIT-SCREEN.)
In order to unlock this achievement, you will need to purchase revive consumables from the card shop by purchasing the $1,000 pack. Once you have ten of them, simply play a game of single-player ops, let a zombie kill you (you cannot use the consumable if you went out of bounds), and use the consumable. Each game of ops will only let you use 3 revive consumables, so you will have to play around 4 rounds of ops, dying three times in each. I recommend putting the difficulty to crazy so you can die quicker.
