EA has detailed the contents of the first expansion for Battlefield: Hardline.

Criminal Activity will add four new maps (Backwoods, Code Blue, The Beat, and Black Friday), two new rides, two new ammunition types for specific weapons, a new gadget, three new weapons, a nailgun battlepickup, a new Bounty Hunter game mode, and six new masks (two animal, four police headgear) to the cops and robbers FPS.

The plot:

There’s been a recent uptick in reports in the local precincts – a rash of violent crime that is seemingly connected somehow.

Small crews of well-trained, aggressive criminals have been using force of arms to terrorize the citizenry and are in direct conflict with the police in many cases. Public property damages and insurance claims have skyrocketed, not to mention the impact on the police force.

Detectives have uncovered evidence of a secret crime ring that could be behind all of this activity. They’re not sure why anyone would coordinate these goals – in a number of cases, the take seems to be smaller than the risk. But, orders have come down the chain to find out what’s going on and put a stop to it. Will you help the police?

Criminal Activity will release next month.
