I think the switchable sounds are for the pack start-up & the idling hum. The wand has the sounds for the basic steam, plus all the video game extras, which you probably knew, but I don't think there was much difference in the 'busting' sounds.So the only way to get the activation sound from the pack is to flip the "new" red switch?
I edited my post like 4 times before you guys replied by the way lol.
Another edit - Now I'm even more confused..
They say we can switch between '84 sounds and afterlife sounds. What sounds will we be switching back and forth from then, if there is no connection to the sound in the wand??
Don't want to say too much for spoiler reasons, but I'm thinking the pack itself had a bit more punch to it's sounds, like it was a bit more powerful due to the way it was used.
