OMG u cant kill someone with grenades OMG the game must really suck.Ur so right about that.(sarcasm)This is not about reach its about halo 4 plz stop being such a whiney ***** complaining about how u cant kill with grenades because someone uses the AA to not die.Im pretty sure the point of every game is not to die so of course the guy is going to run away from dying u idiot.
