Me and my friend are building a level where there is only one zombie at the start and humans can't do damage to the infected. So when round is over the same person is the zombie we looked for the settings for who becomes infected next but couldn't find it are we not looking hard enough or has Bungie screwed us again?
That feature no longer exists...however, I find that the selected zombie is the same for 2 rounds in a row and then it changes.
