For nearly two decades, Firefight has been a Halo favorite, challenging Spartans to team up, hold the line, and survive wave after wave of enemies. The tradition continues this winter as we add the four-player cooperative PvE mode to Halo: Campaign Evolved in a free update.

We're kicking things off tonight at XBOX FanFest, where attendees will be the first to jump in and experience Firefight across new maps and armed with plenty of weapons to help even the odds. 

And there's more on the way. We'll be sharing additional details about this free update at Halo Fest, happening December 12-13 in Seattle, WA, where fans attending the event will also have a chance to play Firefight throughout the weekend. 

We can’t wait to see you all at Halo Fest and to celebrate 25 years of Halo and XBOX together!
