I was think sence they are going back to mk2 fighting experience, that the same way we unlocked noob in mk2, will be the same for this game. they should have it where you can unlock M rated mode. lol

This game won't have any secrets we don't know about. Just like any of the last few MK games didn't... as well as any game in the 21st century didn't. I remember in the 20th century where you pressed a bunch of buttons (konami code anyone?) and you got more lives, or God mode, or infinite ammo. Well, that was a time when video-games were more like arcade fun games you pick-up and play for a few minutes (to a day)... now that stories have become more complex, games have gotten easier, and the videogame industry has evolved, I haven't seen anything of that sort. MKvsDC (just like every other game) won't have any secrets you don't/won't already know about. Also, from what I remember, there won't be a krypt... so I don't expect much from unlockables. I'm sure there will be a few staff pictures in some "Extras" section or something, but nothing spectacular.

Now, if that's not what you were getting at I apologize, I'm not really awake right now.

I really do hope this game has SOME sort of unlockable content to keep me occupied offline. It needs some kind of replay value other than pure online play, cause then most people will have nothing more to explore with the game after completing story mode.

I think the only secrets this game will have is Shao Kahn and Darkseid as unlockable characters after you complete story mode with each universe.
