Recording a warbird
The engine sounds are real. The team recorded a flying CA-18 Mustang at a regional airshow, then layered it with synthesised harmonics so the sound survives a phone speaker's limited range. 'If the engine note is wrong, nothing else matters,' the audio director told us.
The bullet problem
Hundreds of projectiles cannot each have a sound — the mix would be soup. The solution: bullets are voice-managed, with the nearest dozen audible and the rest contributing to a procedural hiss bed that rises with density. Your ear hears 'more bullets' without ever hearing them all.
The bomb that makes people flinch
The signature bombing-run sound is three layers: a real 1944 ordnance recording, a low-frequency sweep pitched to the device's resonant sweet spot, and a very quiet human breath inhale on the leading edge. Players cannot name it; they just brace.
Music that reads the room
The score is adaptive — it shifts with wave density and boss proximity. The team deliberately kept the melodic content sparse so the mix leaves room for combat audio. 'Silence is a weapon,' they said. 'We use it before every bloom.'
Accessibility in audio
A dedicated mono mode and optional haptic mirroring of audio cues came from community requests — a pilot with single-sided hearing told the team which cues he was missing, and they rebuilt the mix around that list.
