Racers against police. Attention! Calling All Units!

Calling All Units is the second expansion of The Crew, and we can choose to be either a racer or a cop. In the story, we will get 12 missions, and we can end up building a cop car with all the gadgets and tuning you can imagine. You can collect parts, other cars, or XP, too.
Quoting the official press release and the features:
Crates

Racers will want to look for crates scattered around the map: they contain all kinds of rewards, and their position is renewed daily. They’ll have to check them out as often as possible. Every time a racer picks up a crate, a chase is triggered and both cops AI and players are alerted. That means that a chase can be either PvE or PvP, but either way, no racer will ever go unnoticed. Plus, any player – cop or racer – can hop in a chase anytime so that a pure PvE chase may turn into PvP at any moment.

Goals

The goal for cops is to catch the player carrying the crate, while other racers help them escape. Each side has a set of special abilities to spice up the race: for example, cops can block their target’s speed or shut down all controls with an electromagnetic pulse, while racers get a blinding flashbang and temporary unlimited nitro, among other cool gadgets. Chases can occur anywhere, anytime: through the city streets of New York on a busy morning, with the snow sticking to the tires in the Rockies or riding off into the sunset in the swampy Everglades. Plus, with changing terrains comes a matching set of vehicles, with their style and sensations.

Vehicles and Abilities

More on abilities will be revealed at a later date.
New exclusive cop and racer vehicles, as well as brand new rides available on both sides of the law, will be available. Cops will also have access to vehicles from The Crew and The Crew Wild Run such as the Lamborghini Aventador or the Hummer H1 Alpha, fully tuned up with police livery and light bar.

Access

Players will not need to complete The Crew to access Calling All Units gameplay. They can access the missions as well as the freeride gameplay after the Prologue.
Players will have access to the racer gameplay, including all special abilities, unlimited free drive chases and a new heat map providing them with the crates’ daily location. They will also get a glimpse of the cop gameplay and mood by playing the prolog mission of The Crew Calling All Units.
Calling All Units requires the player to own the base game to play. The new content will be made available separately and through the digital or retail version of The Crew Ultimate Edition.
The Season Pass does not include the vehicles or content from Calling All Units, but the Racer’s chase gameplay will be free for all owners.
