Ok, this is my idea for super unlockable stages in Mk7:

Along with the regular mystical Mk stages, you can also unlock special stages. These special stages would have little to do with the real Mk world, but instead, would simply be the fun addition of everyday stages, like malls and libraries... Imagine playing Mk in a school gym setting!
For example:

Super Unlockable "Mundane" Stage:
THE MALL:(Shopping Centre to us Brits)

Basically, what you have here is your regular american style shopping mall, complete with escalators, sliding doors and lifts... Mk style; these act as Death Traps!

UPWARDS ESCALATOR:
If you are knocked into this Death Trap, expect to be dragged to the top and then squashed and mangled under the Escalator as it circles under at the end. Then expect, after much blood, flesh ripping and grinding, to emerge at the bottom again as a corpse... albeit, as a mangled collection of flattened meat, before beginning your eternal loop back to the top again and then to the bottom again, back to the top again.... FATALITY!

DOWNWARDS ESCALATOR:
Knock the other fighter into the downwards Escalator and you will see them writhe in pain as the speeded up, mechanical stairway of death, rips into their back, shredding their spine, resulting in gore, and leaving them generally... dead.FATALITY!

LIFTS:
Smash your opponent through the double glass doors of the Elavator and onto the lift shaft floor... Then, the lift will come hurtling downwards just in time to squash the victim into the impact springs... Very messy!
FATALITY!

ENTRANCE DOORS:
The entrance is typical of shopping centres; two glass sliding doors with a weight sensing mat underneath... Except, in this case someone has set the doors to CLOSE, not open when someone steps on the mat... Oh, dear!
You hit your opponent backwards, they stumble onto the mat, and then you get a seen remenescent of that completely daft "Thirteen Ghosts" remake(The part where that guy gets cut in half vertically, back and front portions, by two sliding doors)
FATALITY!


You could also have a Library stage where amidst the furious fighting, books would be flying everywhere!
Of course, you'd still have all the proper, kool Mk stages; these would simply be unlockable additional stages.

So, what do you think?

Post more ideas for "mundane" stages, if you want!
