Battlefield 1's first free DLC, Giant's Shadow, is set to arrive later today for those that have either preordered the WW1 shooter, or own its Premium Pass. For everyone else, however, the DLC will arrive on December 20, and don't worry, it will be equally as free.

In terms of content you can expect to see a brand new map set during the Battle of the Selle, the long-awaited spectator mode, and most interestingly of all, a crossbow that fires grenades... grenades! If that sounds like something you might enjoy, you'll find the incredibly brief teaser trailer showcasing both the new weapon and the new map right below. Have a look:

As for the spectator mode, here's how DICE describes it and its goals:

"With great pleasure, we would like to introduce everyone to the new Spectator mode.  In Spectator, players will be able to join a live BF1 match as an observer.  From there, observers can switch between first-person and third-person camera views of all the players on the battlefield through our Player View mode, get an overhead bird’s eye view of the battlefield in Table Top mode, or fly a camera through the world using Free Cam mode.  

Our goal was to improve Spectator from previous versions of Battlefield.  We gathered feedback from the community and focused much of our efforts on improving the usability and flow moving from player-to-player and switching between the different view modes (Table Top, Player View, and Free Cam).  Another key design emphasis for us was to make Spectator a viable tool for the community to create content which includes a moveable third-person camera, depth of field, and camera filters."

And finally, if you're interested in all of the little additions and changes coming in with Giant's Shadow, you can find the full patch notes by heading over here. There is quite a lot of changes and bug fixes, so make sure to brew up some coffee before you dive in! Enjoy!
