If you know pls reply

Ok so. When I was a kid I saw a zombie movie and I developed a fear of zombie (I can't even look in da dark its looks like a zombie lol) and I want to re watch that movie so I can overcome my fear of zombie but I don't know that movies name. So if anyone know the movies name pls reply. I only know some of the scenes of the movies tho. There was a scene where the mc was sleeping on the tree and hs gun fell as soon as the gun fell a zombie appeared but didn't saw him and another scene I remember is that there was a black person who was friends with the mc and one night when they were sleeping after putting da traps a zombie came and the trap alarmed them but they didn't wake up so that zombie bit that friend and the friend finds his village and then sees his mother dead turning into a zombie and then the zombie affect comes and that friend also slowly turns into a zombie and asked the mc to shoot him while he is still human. And the other scene I remember is the mc is on the jeep with some other soldiers and a women hands them her baby (the women is also turning into a zombie) and I think this scene was in the end of the movie the mc return to the place with humans in there protected by huge walls and I remember the mc giving the pendent of his dead friend to the friends son(?) That all I remember but if u know this movies name pls reply. This is the only place I can ask this question
