How it's made
Source
a stealth-game "spotted" stinger in two parts: a struck impact (broadband noise crack plus a pitched-down body thump) and a bowed-synth style tone that climbs after it.
Body
the impact rings in two inharmonic metallic partials (1 : 2.76 and 1 : 5.4, 0.1-0.35 s). The rising tone is two detuned saw voices a dissonant interval apart (minor second to tritone) with a third voice an octave up; a low-pass sweeps from dark to bright with the pitch, so the tone gets sharper as it rises.
Envelope
crack 1.5 ms attack and 45 ms decay, thump 0.2 s; the tone fades in over 30 ms, climbs exponentially for 0.3-0.6 s, shivers with a 9 Hz tremolo for nervousness, then is cut by a short release.
Variation
`rng` shifts tuning by about 0.5 % and the noise colour; macros set start pitch, rise in octaves, dissonance interval, impact weight and brightness; presets move between alarm, menace and subtle notice.
