How do you complete the hellfire stage it's really freakin hard!?

There are just a few things you need to do:

1. In the owner's room there is a guest registration book on the lower half of the room where you drop the box down the damaged section of the floor.

Get it, go to room 101, use it to unlock that safe on the wall. Get the silver key.

2. Use the silver key to get into room 306 and grab the red jewel on the funny looking tree next to the bed.

Take it to the security room, push the bookcase next to the statue all the way against the wall, and THEN insert the jewel into the statue.

Don't try to put the jewel in before moving the case.

3. Hopefully, your teammate that broke away from you and your partner is in the security room and probably has the gold key, but if they don't just make sure to solve the Europe map puzzle and get it.

Then use it on the locked door of the northwest passage 1 (close to the place where you got the silver key), go in, and solve the puzzle on the generator to start it.

4. If you did the first two items, go out the door that opened behind the bookcase you pushed, and then use the control box next to the emergency ladder to climb down.

Hope you saved a lot of ammo, cause you'll fight the Regis Licker, and several little lickers. Use the lobby bell on the front desk to mess with the lickers hearing so you don't get distracted during the fight.

Be very careful on this one, the one hanging from the ceiling is the main threat, and is somewhat powerful.

I hope that fills in the blanks enough. Now can you help me with the random events on outbreak scenario?
