Surviving a Zombie Apocalypse

"The city was overrun by zombies. My girlfriend, Callie Bernson, the team leader, had taken my best friend, Dan Harrington, and fled in our only armored vehicle, leaving me behind in the shelter to die.Outside, the scratching of claws against metal echoed through the corridors. The defensive barricades were already starting to fail. My heart sank into despair. I raised my gun to my temple, ready to end it quickly, when a stream of floating text suddenly appeared in front of my eyes.[It’s hilarious. That cheating couple thinks they’re heading to Paradise, but that place has fallen. It’s packed with high-level zombies now.][Don’t die, PC! The person in a coma in the shelter—the one your so-called best friend called dead weight and abandoned—is actually the only S-class ability user. Once she wakes up, she’ll wipe the floor with everything!][Just you wait. When your buddy crawls back here in disgrace and finds the big boss awake, he will go to step in and steal the credit for saving her.][Hurry up and die already, cannon fodder. I can’t wait for the tragic apocalypse romance between the best friend and the big boss.]I lowered the gun and sprinted toward the quarantine room. Inside, a woman lay on the bed, sleeping peacefully. I strode over and slapped her hard across the face.“Honey!” I shouted. “Time to get to work!”"
