Welcome to HLP!
Exits are to the rear and left, in case of emergency shotguns are located under the seats. Knife fights are strictly prohibited in favor of more interesting 35mm mortar duels and machete jello wrestling. Heavy weaponry, such as plasma rifles, are located in the weapons lockers, but these can only be unlocked by an admin or a Volitioner. The giant rats in the barracks are not for eating. If you happen to come across a Shivan in the air ducts, don't worry, it's probably just Carl. Toss him your lunch (or your lunch money) and he'll go away. If he doesn't... pray. That will be all, we hope you will enjoy your stay.
Like Japong said, run a search...I'm pretty sure I remember someone asking about this a while ago. IIRC, you may not be able to play the movies ingame if you've got the downloaded version, but I could be wrong.
