Since this is a weapon focused game, it perplexes me that Kenshi the most weapon based character isn't in it.
But enough of me being a salty lil bish, how about guessing the weapons of the DLC characters?
Shang Tsung: uses a sword in the 3d games, but I can see them doing something else with him.
Maybe nothing, and he'll probably have Ermac moves since he absorbed him judging by the intros.
Nightwolf: Probably going to have his bow and arrow, but Sub-Zero stole his tomahawk/axe style.
We might see something different, maybe steal back from Subby and use a Sword, honestly he can have anything really, he's basically Green Lantern.
Sindel: She used a Naganita in the 3d games, which admittedly is a dope ass weapon, just look at Tanya in MKX.
Fujin: it's either gonna a be a broad sword or his plasma crossbow, but the latter is unlikely because Nightwolf is already packing energy arrows.
Hell they might give him a fan for a weapon.
Sheeva: Either nothing, claws, or something new.
I'm leaning towards claws, because Reptile is missing.
Ash Williams: he's an obvious one.
Joker: same as above
Spawn: Like Nightwolf, anything is possible with him, but he'll probably be using a lot of guns...yay.
Terminator: They might give him Sektor and Cyrax weapons, Kinda like how they gave Barraka moves to Alien in MKX.
