Ert held his bat out of the side of the car, clubbing every zombie that he saw.

I was now in the car with soul edge out the other side, slicing zombie's heads clean off

Ert yelled, "Where are we going?" The sound of groaning zombies was almost deafening, and he had to yell to be heard.

A zombie held out his hand, and a zombie ends up biting it.
Carter turns around Callie, clutching his arm, and obliterates the zombie.

(I'm back!)

(You wrote a zombie held out his hand, I think you meant to write it was you who was bitten)

"I dunno." I yell, and take out a sword made of pure energy and sliced through zombies as if they were made of air

(Yea, erthy.)

"OMYGOSHYOUWEREBITTEN" Ert said, taking out a medic kit.

"Lucky" I said, Then a Zombie jumped at me, I cut off its arms and dodged its jaws and punched its head off and kicked it off the car

Ert started applying whatever medics apply on Carter.

I shook my head "No no no, There's no way to cure him now, We need to find and antidote, I'll see what I can do." I say, a zombie bites my shoulder and I grab the zombie's head "Did you just bite me?" I ask it, it nods "BAD!" I shouted and ripped its head off and destroyed the Zombie till it was only ashes

"I heard the antidotes come from zombie guts or something like that." Ert responded.

"That would've been usefull before I slaughtered that one zombie" I said

A horde stumbled toward the car. Ert readied his bat.

I began to glow and became Nightmare, Nightmare's gaze paralyzed the zombies and Nightmare easily killed them
