Is this based around the actual video-game, Dying Light? If so, will we still be expected to role-play completely under the whelms of human realism?

By that, I mean that the character I plan on playing is a Pro Boxer, until Hell broke loose. Using his fists is what he does when there isn't a giant group, since loud noises and wasting ammo is detrimental to survival. I was wondering if I could keep this character, or are we going by The Walking Dead logic, where getting up close and personal is an instant death.

Edit: Of course, he would have protection on his hands, of course. Weaponized gloves or something.
