far cry 4 Xbox 360 freeze.?

It shouldn't be a fault with your Xbox or your disc. It's a problem that the game's developers didn't find when making - - the game, and hopefully they'll release an update that fixes it. I've had games freeze for me too, but it's usually not constantly in a specific place. The only thing that you can really try is to install the game to your hard drive. This doesn't require you to buy anything else, but it does usually require 5-7GB of space. It helps game load and render faster, and with many games, prevents freezing. You can always remove the 5-7GB file that it installs too, if you ever want to.
