Shape Action are now supported in the BGE. A new type of actuator "Shape Action" is available on mesh objects. It can be combined with Action actuator on parent armature. Only relative keys are supported. All the usual action options are available: type, blending, priority, Python API. Only actions with shape channels should be specified of course, otherwise the actuator has no effect. Shape action will still work after a mesh replacement provided that the new mesh has compatible shape keys.
