We got The Dark Below in December but that's hardly the end.
Developer Bungie has big plans for Destiny and that includes multiple add-ons throughout the course of 2015.
We know that one of them is called House of Wolves and it's scheduled for March 10. But now, according to the latest rumor , we'll also get a DLC pack called Comet: Plague of Darkness in September. The information comes from a supposed Bungie production meeting, although there's no way to confirm that. It may feature three new sub-classes, two new weapon types, a new base level, and a new location (Hive Ship).
The interesting part is that it's supposed to be sold on disc, but not as a standalone piece of content. The theory is that Bungie will resell a special edition of Destiny that will include all the extra content for the holiday season, and that's certainly plausible. We always figured this would continue to happen, as the game is really an MMOFPS, anyway.
