In space, no one can hear you scream

Sounds in space/places with low pressure are quieter. You cannot hear people in low pressure environments unless you are next to them (or are them), these messages are italicised.

Based in part on the Bay12 feature, so credit where due to them.

Tested and it sounds really cool.

This is not a feature, this fixes a fundamental flaw with physics :P
You know what, that's not a nitpick, that's perfectly valid, commit incoming.
