Payday 2 is a cooperative first-person heist game released in 2013 and developed by Overkill Software. During loud heists, police assaults arrive in waves, with the Police Assault in Progress status warning players that an active attack is underway. The cue became familiar through gameplay videos, streams, and edited heist compilations. Creators continue using it because the warning communicates escalating danger immediately, even when applied to footage outside the game, especially scenes involving failed plans, alarms, or overwhelming opposition.
