So I normally carry a gun around Incase I run into enemy players, I’ll use L1, the quick equip tab to switch to my knife when I encounter zombies. Well I equipped my knife, or so I thought; as it appeared the knife was in my hands. Well when I attacked the zombie my hits weren’t registering which I thought was odd. My bud said I was shooting my gun as he heard the shots. I didn’t believe him til zombies came from all around. We ran into a house and I logged out and logged back in. After I logged back in I cycled through my firearms to see I had emptied my whole m4 magazine. My buddy was right. Even though I had a knife equipped the game registered it as my M4. This has happened to me 2x. I forgot to report it when it happened, this happened about a week ago.
