Start clearing out your harddrives, because Battlefield 4 will take up a lot of space on your Xbox 360. According to an official post on the EA help site, the first time you start up Battlefield 4 , you will be asked to perform a required installation of at least 2GB of game information. After that, there is extra content that you can install to improve your game performance, 6.6 GB on the Multiplayer disc, and 5.8 GB on the Single Player Disc. All together, that’s more than 14 GB of game data if you want the best Battlefield 4 experience. Of course, you can reduce this a bit if, say, all you really play is the multiplayer, but that’s still at least 8GB of installation, so you might as well go whole hog.
On the plus side, Battlefield 4 is one of the last games to come out before the next generation of consoles hits. So you probably won’t have to do the memory shuffle much more before upgrading.
