I was interested in this game until I saw that it said CD is required.
Is there any way around this? I'm Deaf so playing CD is useless for me.
I know there's an Android app for running the mission (and I assume one for iPhone too), and I think it prints out the events as they occur, so you can see by looking at your screen when a new threat shows up, etc.
But, if other players in your group aren't deaf, then it may not matter; only one or two players are responsible for fiddling bits around in response to the noises on the CD (chosen before the mission begins), so you could make one of them do that. Then it won't matter whether you can hear the CD.
