There has been some discussion regarding warning sounds before, but I guess no actual plans to implement anything has been made as for yet?
Anyway, I listed some of the ones I'm dreaming about, just to keep the topic from getting completely forgotten
'What!? Not that damn flak again...'Ship takes a hit, hull integrity drops below 15%
(high pitched, medium paced "beep beep beep")'Haha!! I finally got you now bastard, enjoy the taste of KAYSERS!!! "tump, thump, thump, thump..."' oh darn...Primary gun is fired, gun energy drops below 10%, triggers max once/min
(medium pitched, fast paced "blip blip blip blip") 'Ok now, got that frickin fighter on my back, but I just need to fire two more rounds and that destroyer is history.... What the FU**! Where did those Tempests come from!?"'The second last salvo of aspect locking missiles/bombs in the bank is fired - need to change attack tactics due to loss of aspect lock/different missile type.
