As per the #ideas channel, I've added blaster noise. You can hear it from a few rooms away, just like when you hear someone yelling. If people like it, and it's not too spammy, I will likely expand it to other noises (hearing general combat going on, ships launching, etc) to add some more ambiance to the game.

NOTE: Added noise for other types of fights (not just blasters) and made it trigger less often.
