BGE patch 18065: gameobj mass writeable + setmass actuator. This patch allows to change the mass of a dynamic or rigid body object during the game. Two methods are available: in a Python script by setting the mass attribute of the game object; by logic brick with the Edit Object->Dynamics->Set Mass actuator. The mass can only be set on dynamic objects and must be a positive floating point value.
