Freeze is a feature in the Battlefield Hardline singleplayer campaign.
When approaching up a group of up to three enemies who are not already in combat, the player presses, flashing his badge and pointing his weapon at the enemies. They will drop their weapons and put their hands up. The player must quickly switch his aim between all of the enemies. If one enemy is not aimed at for a few seconds, he will pick up his weapon and attack the player.
In order to arrest multiple suspects, the player's partner Khai will have to hold her gun on them while the player arrests each one. The player must make sure that Khai is nearby for backup when attempting to arrest a group of criminals. If there is only one criminal, the player can easily arrest without backup.
Note that any enemy that is not present when the player starts the arrest will not surrender if he walks into the scene: he will open fire upon seeing the player. Situational awareness is recommended, by using the Police Scanner to survey the surrounding area for additional threats before starting the arrest.
