According to a post on the Destiny subreddit, Destiny will have a total of 11 crucible maps, 22 story mission, 6 Strikes, 4 exploration areas, and 1 raid. The missions, strikes and raid will all have multiple difficulty levels.
The information was data mined through the Destiny companion app by Destinydb. Although at this point it is not confirmed whether there will be more content included when Destiny launches.
Update: The DestinyDB developer has pointed out that this information appears to be dated June 30, 2014. It stands to reason that additions/changes have been, and will continue to be made up until launch.
Urk also commented on the scale and size, saying
“Destiny’s pretty big. It’s the biggest game we’ve ever made, by far, and we’re sort of known for making games you can play for months, years, and even decades if you’re a little bit…dedicated.
With Destiny, we’re looking to exceed what we’ve done before, not just in terms of scale – the Moon is our smallest destination – but in terms of scope and breadth of activities. That’s true for day one, as you expect, but it also means we want Destiny to have super long legs.
If we’re fortunate enough to have you playing months after launch, you still find lots of compelling stuff to do. That will manifest itself in a myriad of ways, from straight up content to cool activities we’ve yet to show off.
We think we did a decent job supporting Halo, post launch, but we were only ever able to cater to the competitive set. That left a lot of players out in the cold. That made a lot of the team grumpy. We wanted to do better. So, Destiny is philosophically built support every type of player, and all modes with ongoing activities and events. We look at it quite a bit like television programming, as opposed to a singular film, as we had in the past. We think it’s gonna be pretty great, but we wanted to test out a bunch of our new stuff with Beta, to make sure we could flip knobs and levers live, reacting and responding with lots (and, ho boy, did we see LOTS) of players online and playing.
Beta was water wings. Level 8 is nothing. You barely scratched the surface.”
