Halo 4‘s Infinity multiplayer section certainly looks like the bees knees, however that comes at a price, 8gb in fact.
Over on Xbox.com Microsoft “highly recommends” that for the “optimal experience” you should be using a hard drive, however an 8gb USB flash drive will also suffice. This means users who have an Arcade, Core or 4gb model Xbox 360 wont be able to play Halo 4‘s multiplayer without buying a hard drive separately.
Microsoft suggest purchasing a pre-configured Xbox 360 USB flash drive by SanDisk which are available in 8gb or 16gb varieties. Microsoft also suggest the 320GB media hard drive that comes with a downloadable copy of Lego Star Wars 3: The Clone Wars.
No doubt this early warning is a sign that Microsoft realise they could be facing consumer complaints when Halo 4 releases as they had to deal with a flurry of disgruntled gamers when Halo: Reach launched.
