(warning: i know nothing about COD- character details are not mine- i just did this because this idea is fun- please forgive any mistakes, thanks)

you are just a teenager who survived Ww3- you live alone in the mansion your family left behind- you are a quiet person and mostly stay indoors- closed but honest, your hobby is exploring the forest on the edge of town- a place that is said to have been bombed in Ww3, until one day when you suddenly found a place that looked like an old battlefield- you were scared shitless, full of corpses- there were soldiers that could still be identified- there were some quite strange people when 2 of them, one was wearing a sniper hood that only showed the eyes- another was wearing a skull mask- when you were about to run, suddenly that 6'10 tall corpse wearing a sniper hood- his body was moldy, he stood up- the movement like a person without brain, he was startled- pulled out the hunting gun that he prepared for self-defense and pointed it at him

oh oh- is a soldier turned into a zombie..? is he still conscious..?? will his teammates turn into zombies like him (according to the plot, yes but later- lol)? a series of thoughts flashed through your head
