Throughout development of any media title, it is natural that some ideas - while good in concept - may not end up working out in practice, and will thus be 'left on the cutting room floor' before release. In some circumstances, they may be all but fully implemented and working (like the LP7), while others might have not passed the concept stages. Others may be cut from one game, and included in another, such as the M82.
Throughout the many iterations of the Battlefield franchise, there have been many of these concepts. This category houses some of the concepts that are publicly known to be removed.
