That's right, now your "Destiny" character can do Drake's infamous "Hotline Bling" dance whenever you like. In "Destiny," it's just called the "strange dance," probably to avoid a lawsuit.
This is Drake's version of the same dance, for comparison's sake:
Unfortunately, this dance move isn't a free item. Like other "emotes" in the game, you'll need to purchase this dance move from the new Eververse Trading Company, which sells cosmetic items in exchange for your hard-earned, real-world dollars.
To buy a dance move, you must first purchase Silver, an in-game currency in "Destiny," with your real money. One Silver costs one cent; most dance moves cost either 500 Silver ($5) or 700 Silver ($7). The "Hotline Bling" emote costs 500 Silver.
There are other dance moves in the Eververse store, but this is easily the best one. Bungie, the maker of "Destiny," has been consistently offering new dance moves for players to go out and purchase since October, but they're only available for a limited time until a new batch of moves comes along.
Personally, I'm still rocking Michael Jackson's "Thriller" dance, which was added during "Destiny's" Halloween event, "Festival of the Lost."
