Whenever you’re done with your expedition, it’s a good idea to head back to the Tower, a hub city where you can offload vendor trash, purchase anything that might help you on later missions, and train your class abilities. It’s very similar to cities in most modern MMORPGs; dance parties tend to break out in unconventional (and incredibly unsafe) areas, while other adventurers appear to be all business.
Destiny is shaping up to be quite the experience, and with the beta just beyond the horizon, it’s exciting to see what Bungie will have to show us next. Of course, we’ll be here with new information as it becomes available, so stay tuned!
