In the run-up to the holidays and the release of its 30th Anniversary expansion for Destiny 2, developer Bungie has been running a sale on its store called Gjallardays. Named for the vaunted arrival of Gjallarhorn, a Destiny 1 favorite, in Destiny 2, the Gjallardays event is like an advent calendar of Bungie sales and Destiny 2 freebies--as well as a chance to win stuff.

Today's entry in the Gjallardays advent calendar doesn't provide anything free, per se. Today, tweeting about the Gjallardays event before 8:59 AM PT / 11:59 AM ET on December 1 enters you into a sweepstakes to win the Collector's Edition version of the upcoming Destiny 2 expansion, The Witch Queen. You can find the full details on the Gjallardays site.

The Witch Queen Collector's Edition is a pretty impressive item, if you're a big enough Destiny 2 nerd. The set has been sold out pretty much since it was first announced back in August, and comes with a host of both physical and digital items.
