Overall it's totally fine. The other day while doing VoG we had 2 kids in the party, it was totally fine until we reached Gorgon part. Dude both of them started to run, punch, jump constantly and babbling some noices into the mic i thought they were daemons. They would'nt stop and on top of that they bursted into evil laughter. Fireteam leader had to kick them. Funny part is, when we kicked them they were as silent as before. Once we finished the gorgon part he re-invited them and everything went fine again. That was a strange experience.
