Assassin’s Creed Black Flag “Killer Killer” Achievement not working

I’m playing through Black Flag and unfortunately my Killer Killer achievement isn’t popping. I’ve harpooned about 12 killer whales, and I’ve tried different things to see if I was doing something wrong but no luck. I also deleted the game and then re-downloaded
it, but that didn’t help either. If anyone has any recommendations to help with this, I’d love to hear it. I have 100% sync on the story, and I’d really like to have this achievement, especially since it’s one of the easier ones to attain. Thanks in advance
for any help!

Xbox One Assassin’s Creed Unity Bundle

I just bought the Xbox One Assassin’s Creed Unity Bundle. I redeemed the code, it downloaded and installed Unity but not Black Flag. On the Xbox One box and front of the card it shows both Unity and Black Flag. How can I get Black Flag to download?

Assassins Creed Black Flag is only £5.99 as well, mighty tempted....

 

Sorry to hear that, RedHood435!

The steps and info in our Achievement Sticky can help you troubleshoot that further; if you're still not seeing that achievement unlock after following those steps, make sure to fill out the survey linked at the bottom
of that post. You may not hear from them directly regarding this specific achievement issue, but that info goes to the achievements team so they can investigate further to identify and help address any potential issues.

 

Thank you so much for your help. Unfortunately none of that worked, but that’s no problem. I just wasn’t sure if it was something on my end. No worries. Thank you again for your help.
