Modern Weapon System in the Zombie Apocalypse

Riku Hayashi was a high school student who was addicted to playing mobile games. During his free time in the school, he was playing a zombie apocalypse game known as Armory: Dead Zone Protocol.While playing it, there was a scream from the outside. Zombies came out from nowhere and were on a rampage, killing every student on sight. As he was attempting to flee, he tripped and knocked himself out.When he woke up, he found himself inside of a bloodied classroom and a floating holographic interface. And it was familiar. It was the same interface in the game he was playing.There, he realized that he had somehow gained access to an in-game system where he could level up, gain experience points, and purchase a variety of weapons, from handguns to military vehicles. And he is going to use it to survive and possibly save humanity from extinction.P.S: This is my first time writing a novel, so if there's a mistake you found, grammar, punctuation or any errors, please comment it so I can fix it. I was inspired to write this novel because I binged-watch a lot of zombie series like All of us are Dead, Zom 100, High School of the Dead, World War Z, and other related apocalypse story like the Alice in Borderland.I hope you guys enjoy!
