Please don't flame me too much for this,  I'm old.  I downloaded the Broken Steel DLC for the PS3, but how do I start it?  I clicked on Download content on the Menu, then hit Continue. 
I started playing, and a prompt came up saying (I think) about the level cap being higher now. 
 
But isn't there more to it than that?  I know  you can keep playing after it ends, but is there more to it than that? 
 
I had already beaten the game, and started a new one.  That's where I am now.   So there are no different objectives, just play the game as usual? 
 
Thanks.

I see, so after finishing the main  campaign it does add something else?   Cool.  Wasn't sure. 

Yeah, when you finish the game the end of the game by itself will continue into Broken Steel.

" @killer_meatballs: Whenever you install a DLC, it will automatically be loaded into your game a few minutes after starting your save up. In this case, Broken Steel raises the level cap to 30, makes it so that you can continue playing after the final quest, and also adds a large new questline after the ending. Once you see the message saying the level cap has been raised, you're good to go. "
