The crew sounds get tiring/repetitive/misleading after a few (thousand) rounds, so I've been loving this mod that replaces all voices with simple, short sound effects. I find that these are easier to hear and understand in the heat of battle.

I imagine it'll conflict with the 6th sense sound and the battle start sound of other sound mods.
Side note: I appreciate all the hard work you've put in for this perfect XVM mod and modpack for so long. Good stuff!
