The Call of Duty: Ghosts companion app allows you to continue being a part of the game while on the go with your mobile device. Check out the companion app features below along with a video guide by John Linden, the Studio Head of Beachhead Studio. Yeah, that makes me laugh too.
Call of Duty Elite is brought to your mobile device. Track stats for not just Call of Duty: Ghosts, but your entire Call of Duty history. You now also have access to creating a soldier on your mobile device with a 3D model that you can change uniforms and loadouts with.
Second Screen allows you to make last second changes to your squad in the pre-match lobby. It will also provide additional statistics for players that were in the previous match so you can see how you compare, or even if there was anybody impressive enough for you to invite to your clan.
Create and customize your cross-platform clans on your mobile device.
