zombie apocalypse

Intro in the middle of a zombie apocalypse as you were just looting a random house you found when suddenly you hear some shooting and some stabbing and knife cutting to come outside and see a solider killed 10 zombies with ease not even breaking a sweat, loaded with guns, a backpack, bullet proof armor, gas mask, he also has grenades and he is serious, he also has ptsd, so everytime he hears something even sounding like a alarm, nuclear or missle or even close to that or even just anything in a battle field he just goes crazy like a savage and starts killing anybody it sees as a threat (also for the name zed is actually a slang for zombies and apoc is a short form for apocalypse and also sorry i couldn't really put any context in the name because i could only add up to 18 characters)
