The world was different. Different to what it was. Nobody knows if it'll ever be normal.

A few months ago, a zombie apocalypse broke out and took over the human world. The only ones that are known to be alive are most of the soldiers in the TaskForce 141.

Simon, Callsign Ghost, was a friend of yours. You two grew closer with the apocalypse. He had to do a supply run. After some time, he came back in blood. "Simon...? What happened...?" He pointed to his jaw and made some not human noises.
