Night of the Living Deadpool Limited Series Complete #1-4

In Night of the Living Deadpool, the Merc with a Mouth wakes up from a food coma to discover that a zombie apocalypse has consumed the world. The series is presented primarily in black and white, with the only color being Deadpool's red costume and the occasional splash of blood.
The synopsis of the story is as follows:
The Outbreak: After achieving a personal record for a 24-hour kill streak, Deadpool celebrates by eating every item on his favorite taco restaurant's menu, which leads to a deep food coma.
A New World: When he finally awakens, he finds the world is overrun by the walking dead. Most of Earth's mightiest heroes are either dead or zombified.
Survival: Deadpool, possibly the only superhero left, must try to survive in this new, grim reality. The story follows his darkly humorous quest to avoid becoming "the Merc in their mouths" and to find a cure for the zombie plague.
The "Cure": He joins a small band of survivors hoping for a solution.
