So I played Tranzit yesterday splitscreen with my brother on a custom game. I went down on round 15 and he didnt revive me. I came back round 16 and thats when i noticed the glitch. The zombies made no noise, and there were no drops. We didnt get a drop for the rest of the game, we got to round 21. There was sound for everything, shooting, talking, everything but zombies yelling. The zombies made noise before then and we got plenty of drops. Very weird glitch.
