Police Assault

Police assaults is a gameplay mechanic exclusive to Loud. When an assault begins, a police badge with text that reads "UNDER ASSAULT" (both in the color of the selected difficulty) will appear at the top of the screen, flashing between 0% and 100% opacity at 2-second intervals. Waves of enemies will constantly attack the player, with their health values, damage output and types scaling with difficulty. The music track associated with the heist also changes with each different stage of assault. Jade will warn you of the current stage of the assault, such as "Cops ETA in 20 seconds, get ready!" for Anticipation. She will also notify you of special units like snipers and SWAT vans appearing.

Once the assault ends, the police badge shown at the top of the screen disappears.

Control
Control is the initial stage that begins immediately after raising the alarm or the conclusion of the Fade stage. First responders will arrive on the scene, followed by the off-screen spawning of riot shields and groups of officers called "assault teams".

This stage can be made to last 30 seconds longer with the Delayed Response asset.

Anticipation
Anticipation is the second stage that begins after assault teams have spawned beyond invisible walls. It lasts for 30 seconds, depending on difficulty. Assault teams cease spawning, with riot shields starting to move in. If playing on difficulty or above, cloakers will begin spawning in dark, obscure locations.

Assault
Assault is the third and main stage of a police assault. It begins after the Anticipation stage. All enemies will begin charging at the player, with a majority of non-special enemies part of assault teams. This stage lasts for about 5 minutes.

Fade
Fade is the fourth and final stage, taking place immediately after the Assault stage ends. Main forces will retreat while Hostage Rescue Teams will try to free Hostages and Technicians will try to retrieve bagged loot. If there is at least one cable tied civilian, this stage will last longer.
