NetherRealm Studios director Ed Boon enjoys using his Twitter account to rile up fans with hints and teasers. Yesterday he struck again, leaving some fans speculating whether or not Mortal Kombat will end up getting the crossover treatment again.
Granted, Boon has quite a bit on his plate currently with the Injustice sequel, so it's doubtful that this tweet confirms that there are plans already in the works, but it is good to see Boon at least weighing his options as far as where he can take the Mortal Kombat franchise in the future.
