Battlefield Hardline features new variety of gameplay that breaks away from the traditional Battlefield game modes. The focus of the game has been shifted to police and the "war on crime", breaking away from the military setting that has hitherto characterized the series. As such, the main factions in Hardline are the police Special Response Units and criminals. Players will have access to various military-grade weapons and vehicles, such as the Lenco BearCat, as well as having police equipment such as tasers and handcuffs.
Hardline also uses the Levolution mechanic from Battlefield 4. For example, in the map "Downtown" players can send a construction crane crashing into the building, ripping down debris from the central buildings in downtown, which falls down on the streets of Los Angeles. But, this time, every map features multiple levolutionary events, both small and gigantic.
