Can any one tell me how to get through Hell Fire?

Okay, to answer your question you dont need the battery for anything go to the owners room and move the crate to the hole.

Then climb down if you have the gold key use it on the door with the gold relief on it.

Then go in the room and you will find something then once you get the silver key from someone else use it on the third floor in the room that needs the silver relief.

Find the red jewel then go to the secrurity room and move the bookcase near the statue, then put the red jewel in the statue then go in the door and then you can do the rest.

To get through hell fire you have to get the red jewel on floor 3 in the room that needs the silver key.

Then once you have it you go into the security room and go to the book shelf, move it then you can place the jewel in the statue.

Then go through the door and get ready to shoot something near a vent good luck and a tip.

Use any herbs or spray to stop the virus for a second I made it through with the virus up to 20 percent.

At the east end of the 2F corridor you have to use a card key.

You keep going all the way and the two doors near the end of the hall lead to the owners room.

You have to push the crate down the hole jump down.you enter the door go down the hall and on a door you have to use the gold key.

In that room you have to figure out a puzzle the way it goes is by rows left to right.

You have to push the second button in the first row then push the first button in the third row,second button in the third row,second button in the second row puzzle complete.

Oh yeah you are timed when doing this.then enter room 101 you will see a safe on the wall and on the bed theres a paper.

You put in a code for the safe depending on what name is on the bed. Mr. Andrew Evans JIA Ms. Anna Lowell BAE Mr. Toby Whitman DCH Mr. Joseph Wilson GGF then the safe opens with the silver key
