26th April - Jason Voorhees (12 days after game launches)
10th May - Tremor
24th May - Predator
7th June - Tanya
Now, based on past NRS games, MK9 had 4 DLC characters from April release to August~, Injustice had 6 from April release to August~ also. So they're clearly getting a lot faster at doing these characters.
I reckon a second Kombat pack feating 4 characters could be in the works, that'd bring us up to August.
If so what other 4 characters would you want to see? Sektor, Reiko, Sindel and Havik IMO. (I think Fujin is gonna be a secret character!)
