Deep Silver has confirmed that Homefront: The Revolution will release on May 20th in the UK and Europe, while North America will get access to the game from May 17th. The latest trailer is called This Is Philadelphia and is set within what is called a Yellow Zone in the city, These zones are where the vast majority of the population live, and are under constant surveillance. The Resistance is present within these areas but act much more like a guerilla force, disrupting order and seeding discontent among people.
Homefront: The Revolution will get a closed beta on Xbox One, and those who are interested will be able to register on the official site. This beta will take place in February, and will feature a number of co-op missions.
