If you get the error code POLANA, it is very simple to fix. You do not need to unplug your router or anything like that.You will need to exit out of the game completely, go to settings, all settings, power and start up, if you have it on instant on then turn it to energy saving, press b, go to turn off or restart, it should be right next to power and startup mode in power and startup settings, select it then do full shutdown and fully shut down your xbox. Then turn it back on, go into IW and start up zombies and it should work.
I have tried this technique multiple times as well as hard resetting and the error code still comes up. I'm am very irritated with this because this is such a simple issue to fix and yet nothing is done. I honestly am not getting my $130 worth and this is extremely unsettling. Plz help!!!

You must install on the INTERNAL hard drive for the game to work. Just like with Hardliners.
