I am playing batman on pc. Now the problem is that i have finished the two phases of fighting with ra's al ghul. i am stuck on the last phase where he's threatening to kill her daughter(Talia al ghul) with a knife & telling batman to kill him. But here my batman jsut stays like a statue & do nothing. I searchedon the internet about this & i found that at this stage a reverse batarang gets automatically unlocked but its not happening with me. I tried playing the main story thrice but to no avail. Its making me depress now coz its my fav game & i am not able to play it..plzz sum1 help..i'll b glad..thank u..
