A repository of Halo information is now at your fingertips. The Halo Channel app has become much more inclusive. Previously, it was only available on the Xbox One and Windows 8 devices, but now Android and iOS users can access it too.
The Halo Channel application allows people access to walkthroughs, stories, original videos, and more, all based on the series of games. There’s even a Halo Encyclopedia. All of this is free, so no need to worry about in-app purchases if you grab it from iTunes or Google Play .
The only platform that don’t have access to the Halo Channel is the Windows Phone. That will come when Windows 10 mobile launches, meaning it should hopefully be around in time for the October 27, 2015 launch of Halo 5: Guardians .
