Nightfall ASAP!!!

I got Nightfall to play if i selected Nightfall then Details and then Play

Hey there R00K008!

Sorry to hear about the Nightfall issue and thank you for providing the detailed information. Do you have any guests signed in while trying to play Nightfall? Also, was your Nightfall code redeemed using the same profile you are trying to view Nightfall
from?

Having a similar if not the exact same issue. I have the hard copy of MCC, installed the Halo Channel, and used the code included with the game to get Nightfall. When I open the Halo Channel and go to Nightfall, the only option it gives is to Buy Nightfall.
Even when I hit that button though, it takes me to Nightfall in the MS Store and says I already bought it. Even so, it won't let me play it, it still says Buy Nightfall. WTF?

Hey there headshot10101!

Sorry to hear about about the Nightfall issue! If the issue is continuing to occur, I recommend trying a few additional steps:

• From the Home screen, navigate to My Games & Apps.
• Under the Apps tab, select the Halo Channel and press the Menu button.
• Select Manage and check to see if Halo: Nightfall is under the the Ready to Install section.
  
• If Nightfall is under the section, select Nightfall and then select Install.
• If Nightfall is already showing as installed, select Nightfall and press the Menu button.
  
• Select Uninstall. Once Nightfall has been uninstalled, press and hold the power button for 10 seconds.
  
• Once your console has powered off, wait a few minutes and then power on your console.
  
• Navigate back to My Games & Apps and select the Halo Channel.
• Press the Menu button and select Manage App.
• Under the Ready to Install section select Nightfall and select Install.
• Once Nightfall has installed, launch the Halo Channel app.
• Select the Originals tab and the select Nightfall.
• Try viewing an episode to see if the issue continues to occur.

Give the steps listed above a try and be sure to let us know how it goes. Thanks!

@Psycho3849 Look at the picture of the achievement. It is the symbol of Nightfall on a folder. The achievement is only telling you to find all intel on Nightfall.
