In attempt to keep everyone on the same page and prevent confusion/complaints, Microsoft has confirmed that Halo 4 Multiplayer will require the use of an 8GB flash drive or 8GBs of free space on your Xbox 360 hard drive.
Those of you who own a Core, Arcade or 4GB S model console will have to make an upgrade somewhere. Whether you decide to go with an 8GB flash or a full-size Xbox 360 hard drive is up to you. Obviously, Microsoft recommends you snag one of their official Xbox drives by SanDisk, but most flash drives will work. For “an optimal experience” Microsoft recommends players go with the full hard drive option. Here's their statement...
At a minimum, you’ll need at least an 8GB USB flash drive or a built-in Xbox 360 hard drive to play Multiplayer mode in Halo 4. For an optimal experience playing with an Xbox 360 Hard Drive is highly recommended.
Halo 4 may be the first game to require this amount of space for multiplayer gaming, but don't expect it to be the last. As multiplayer gameplay continues to push boundaries hard drive space could become increasingly important.
Do you game on a Core, Arcade or 4GB Xbox 360 console? Which option will choose for your Slayer fix, flash drive or full-size hard drive?
