This is a pointless feature that does nothing but confuse people who are just base level trying to understand their bearings. Thanks to wolfen90 on reddit it is really simple:
Once you open shootergameUI, either with notepad, or notepad++,
change [ShooterGame.SGUIHUDMiniMap] m_bUseRotatingMap=true to [ShooterGame.SGUIHUDMiniMap] m_bUseRotatingMap=false
There really should be more done with the minimap in this game. It looks like such a placeholder right now.
