On the Xbox store There is solo Spartan assault and not strike why?
I guess all Halo fans would love to see Spartan Strike on Xbox, too.
Unfortunately, they ain't doing it 'cause it's their marketing strategy. They want you to buy Windows Phones and other platforms with Windows OS.
The way they think is "If people really liked Spartan Assault they are probably going to buy the next game (Sparten Strike) even if it's not going to be on Xbox. They would even buy a new Phone or switch their OS just to play it."
I think they will release it on Xbox eventually. Either if they've sold enough of their devices/OS or if they see that the strategy ain't working and they might as well just release it for Xbox.
