Looking for a zombie game ?

Ok. I don't know but I think I woke up from this game twice so I have to ask or I will go crazy.

I don't know the platform.

I only remember that it is about zombie. So a town or family was infected and turned into zombie.

The big guy not sure if he is the protag after several attempts to kill the zombies and failed, came to understand the zombies more. Big guy seems to be the town butcher and the only one who hasn't turned. They are just undead that was unfortunately turned undead. They can't speak but they don't want to hurt anyone. That is until the hunger takes over them. I think the big guy decided to kill people to take care of them, controlling their hunger. Not sure why.

We got another protag. This guy is a college student. I think the big guy decided to kill him to feed the zombie as he somehow got lost and stumbled upon the zombie town. The student survive and after some fight with big guy, he decided to help the zombie too. His true reason is because he fell in love with the zombie girl in the town and he was a nerd that had never had anyone he fell that way.

I think the main antagonist is the military as they were responsible for the mysterious contamination of the water of the town and turned everyone zombies.
