This morning I saw Halo Wars was now backwards compatible. I got really excited, and immediately went and found my disc and installed it on my Xbox One. From the few hours I've played it, it's been great.. No real issues with frame rate or anything. However, when my friend and I tried to play with each other, we came across a major problem: Whenever I use the Xbox 360 Menu to invite him, it starts a game. This is because you press the back + start button to bring up the 360 menu, the start button starts the game. I see no way at all to join up and play as a group at the moment. Is there a fix for this? Am I just dumb and I'm missing something? Any feedback would be awesome.
