Place it at the turning point after the setup and before the peak action. Lead in with a danger alarm sound effect to build the alert, then follow it with the FBI Open Up sound for the breach moment that sells the raid.
Über diesen Sound
This is the roughly sixteen second Police Assault in Progress status cue from Payday 2, built from sharp warning tones over a driving electronic pulse. It feels tense and urgent, like pressure spiking all at once and a situation slipping out of control. The cue comes from Overkill Software's 2013 co-op heist game, where it marks police waves hitting during loud heists.
