 * MK2 which features several improvements:
 * - uses generic throwable code, reducing boilerplate nonsense
 * - uses approach-based interpolation, preventing desyncs and making movement silky-smooth
 * - new adjustments in the base class allow for multiple MOP impacts per frame
 * - also comes with tons of legacy code to ensure compat (sadly)
