Apone isn't in combat gear because I don't f**king know :S
And Vasquez isn't included because I don't f**king know! No one knows, except Gearbox.
Maybe they couldn't secure the rights for her specifically, maybe they (sadly) only let you use male players in mp, maybe they just thought these 4 were the best to include, maybe they know people want Vasquez and thus are saving her for paid DLC, we'll find out, now stop clogging the thread with useless questions at nothing.
And stop hitting your face boy, it makes you seem a fool
