So it sold around 10% of the install base compared to cod aw which had close to 30% of the install base when it launched. The attach rate for x1 this gen crazy if we look at other games. But halo did bad. Way below my expectations. This might have to do with 343. Im interested to see how gears of war does next year. Wanna see if it will be in the position halo is or if it might become xboxs new flagship title.
