I'm glad I'm not the only one! Same exact problem. Got Jacqui with no issues, but despite doing like 20 stage fatalities with Cassie....nothing!

I'm just going to buy the silver tier Cassie card for 50,000 gold and do the multiplayer towers with her to unlock the console costume

I had this problem yesterday, I just kept doing stage fatalities and checking the app every now and then. Eventually, after probably an hour of gameplay the darn things finally unlocked.

So there is hope

I have the same issue. I bough a Jacqui card and unlocked the cyber Jacqui fine. Then I didn't have enough to get a Cassie card so I too have been doing multiple stage finshers with her but it doesn't unlock. Funny thing to mention, I have klassic Kitana but on the mobile app it isn't checked off either?

I've reached level 50 in a faction multiple times, yet no Injustice Scorpion on the mobile app. It's so weird how this stuff occasionally works.

to unlock undercover cassie on mobile you need to do three stage fatalities, one each in the pit, the kove and refugee camp. simple as that.

I also can't unlock the cards on my Android device. Did it so that they're checked off with the 'Claim' option but the app closes everytime and never gives me the cards. So frustrating.

Just need a login for a homie?

The trick is to use each stage, not just replay the same match on the same stage three times.

Speaking of unlocks, (I couldn't find another more appropriate thread) my friend is trying to get me all the unlockables on my mobile version as i'm helping him unlock all the skins for his console.

Anyway, he just got me Cassie & Jacqui, which is cool, but we haven't worked out how to unlock Klassic Kitana. The instruction just says 'Take first place in a Tower Battle'. This is a bit vague since all towers are for battles and he's been going through each type of tower since the spring last year. So exactly what does this mean?

Tower Battle is online. A bunch of guys go through the same tower and best score wins.
