At the main menu, select "Options" and choose the "Blackout" tab. You can then change your mini-map from square to round. The square mini-map does not reorient as you move, but the round mini-map does. The round mini-map should be more familiar to Call Of Duty veterans. Using the round mini-map may improve your navigation skills.
