At the end of the Batgirl game play it says

Batgirl available though Season Pass

Killing Joke Pack Sold Separately

1. Joker
2. Batman classic costume
3. Red Hood Joker

Any guesses?

maybe a new Batgirl alt?

Idk Lobo didn't get one, If she does I hope its not the clothes she had on when she was shot

Yeah, I was kind of wondering about that earlier, too. I could only come up with the 2 you did for sure, the Joker skin they already revealed and the classic Batman costume. Beyond that, my only guesses are a plainclothes Barbara Gordon (hopefully not the ones she was shot in... that would just be creepy), or either Batgirl's classic costume or her New 52 look (even though she was not operating as Batgirl at any point during the actual story). I don't know... hopefully they'll announce it soon.

@spidermonkey2099: I was thinking the same thing, since 'Batgirl' wasn't apart of the story why would she get a costume. She could get a classic alt, but Lobo didn't get an alt yet. So my guess is Joker will get 2 and I would be fine with that.

@avenging_x_bolt: I meant that Lobo, as DLC, did not get an alternate costume, so I don't see her getting one.

i know what you meant. i just don't see why that would have any effect on a costume pack.

@avenging_x_bolt: Well that and that its called Killing Joke pack. Batgirl didn't have a role in the book. So I have no idea who the 3rd skin might be for.

@avenging_x_bolt: @spidermonkey2099:

Red Hood

@ccraft: Red Hood would make sense (and would be pretty awesome).

@spidermonkey2099: Agreed :)
