I've been playing the Force Unleashed for a long time and am very close to getting all the achievements of the game, but one really just doesn't make any sense to me. The achievement of 'Launched' requires killing 100 enemies with grapple moves, but moves like Sith punt just don't work. Or at least I don't know if I get it right. What is a grapple move and is there anything that would help?
When I press attack (B) and jump (A), I just swing the lightsaber and jump and that's all. Am I doing something wrong? Thanks
