Pure insanity for the upcoming Tiandong Heavy Industries 2.0 update, it makes me laugh on occasion while playing the game even! I hope players feel the same way, as yea now it plays from a large selection of various guitar clips when you activate its ship system. It is even a real live guitar played by fellow Starsector modder TomatoPaste, not a MIDI sequence and samplers!
And for those that find it annoying, no worries. You can disable it outright or even contextually, for example in tiandong_options.ini.
# Controls whether the Liberty's ship system should play a guitar when activated, depending on who is flying it.
# All three default: true
"americanGunsPlayGuitarForPlayer":true, # Player piloted
"americanGunsPlayGuitarForAlly":true, # Friendly or ally piloted
"americanGunsPlayGuitarForEnemy":true, # Enemy piloted
But personally, I feel it fits this Interstellar Bounty Board ship where one can stretch the limits just a bit heh.
