After executing the general in the 2nd basement. I am not able to find a way to open the door and get the hostage out. Could any help me with that...

first u should kill a chef wen he come inside the toilet and take his dress then move on to the kitchen and kill the security near the secret way to the basement and take his dress and move to the pleasure rooms the entrance is near to the toilet and meet a old lady and go near to a lady in the room near to the old lady and she will guide you to the backside of the kitchen and she will hand over the safecombination. then u move on to the kitchen and go down to the basement were u can find the hostage.be careful dat u never skip the dialoges because on these dialoges he will say the safe location so u should go there and collect the figure and take that to the lobby near to the bar and take the poison from the lobby and come to the kitchen and take the chefs dress and poor the poison on the food which is kept on the table and then carry it to general and the security will have the poison.u should immediately drop the gun using - button then change your dress from the kitchen and move to the lift on the basement through the secret way in the kitchen and move to the ist floor were u can see the general kill him using the knife wen he move to any of the room then get out of the hell through a small door and get to the boat near to u thats all if more doubts mail me on sterinash@gmail.com
