I must say that is one good-looking Xbox 360 right there!
For $399 it can be yours along with
2 Wireless Halo 4 themed controllers
A standard copy of Halo 4
A Xbox 360 black headset
“Custom content” You get a token for some DLC.
As far as the Xbox it’s mostly just a Xbox with all the features. It has a 320GB hard drive so you won’t run out of space on it ever, as well as has built-in Wi-Fi.
