As you can see in the image above, House of Wolves may allow players to take a trip to the asteroid belt and visit the "Reef Social Space." Though it's unknown exactly what the social space is, it may refer to an area akin to Destiny's Tower, where players can shop, pick up missions and interact with each other in non-combat situations.
Bungie may have teased that upcoming social space as far back as the Feb. 20, 2013, video that revealed Destiny's PlayStation 4 version, and you can see that brief tease in the GIF below.
The other images posted on Reddit show a new strike, a new crucible playlist and two single-player missions designed for high-level characters to battle on the moon.
Early this month, the same redditor, megamanexe64, unearthed other purported House of Wolves details that included information about gear, weapons, level caps and the expansion's release date.
Bungie was quick to respond and warn players that what you see might not be what you get, given that House of Wolves is still in development.
"Aside from giving it a name, Bungie has yet to reveal the House of Wolves," David "DeeJ" Dague wrote at the time. "That means that anything you know about it can change. We have a team working on the experience in their own fancy room, and they have some exciting surprises up their sleeves."
Shortly thereafter, DeeJ revealed that House of Wolves would arrive sometime between April 1 and June 30. That will be Destiny's second expansion, following The Dark Below, which was released last December.
