Well, to start this off...
I will choose 1st person, and for the story...it has been 5 years after the begging of the first zombie attack, you are a soldier and you have been assigned to go into a largely populated city to kill and burn the last remaining zombies. After you are sent over there with a helicopter and doing your duty, an unexpected horde of zombies comes out, the helicopter is destroyed with the pilot inside and all that's left is you and two others. Pretty simple.
