The original Gears already had a violence filter, which retained the profanity but turned chainsawing a person into a kind of theraputic act, like shiatsu. The sequel takes this further, with what sounds like an alternate audio track - like a radio-gelded version of some raucous club banger. That's the first time I've ever heard of unique vocal content without a technical or geographical imperative, which is really interesting. To, um... me.
