'Halo 5' will run in 'true 4K' on Xbox One X

Halo 5 is getting the "true 4K" treatment with the Xbox One X. During Halo 5's pre-release hype cycle, Microsoft said that it was so focused on hitting 60 frames per-second with the game that there weren't any sacred cows -- including split-screen co-op, a series staple. Maybe don't expect that to return with the Xbox One X's more powerful innards, though.
