I'm currently (re)watching "Space: Above & Beyond", and was terribly confused why the beep beep noises the silicates make feel so terribly familiar when the last time I watched this show was back in the 90s.
And while watching another episode during my late lunch break just now I realised: it's the same sound effects used for the acknowledgement sounds in the indie game "Duskers"!
Mystery solved, thank fsck, this was driving me crazy!
