Love spending a few hours playing this on the iPad but sadly it's being ruined with cheats using keyboard / mouse controls. Pathetic bastards are not good enough to play the PC version so take easy wins against those using touch screen controls.
The new COD mobile version has a battle royale mode and it's controls are meant to be very good for a mobile game. Made by the same people who made PUBG mobile too I think. It's got an auto-detect on to stop keyboard and mouse players being matched with normal controls.
