This game was once one of my favourite mobile games of all time but that was in the past 3-4 years ago. It was a time when the menus dident lag your phone and arena challenges existed you didn't need the internet to play it, cars didn't have levels and heads had no health it was just a dual between cars to see who hit the opponent first now it has lost nearly all its defining features. This game has sold its soul for money and I can only ask the developers was it worth the cost.
