the cramped halls of the apartment.

Guide to navigating the cramped apartment halls in Left 4 Dead. Find items, use explosives wisely, and choose your path through the streets or warehouse to reach the subway safe house.

As you reach a small square area filled with some broken down vehicles, keep an eye out for goods; there is a second pistol waiting for you somewhere in the level. Check the storage room to the left to see if anything (or anyone) is waiting inside.

Using an explosive weapon such as a pipe bomb or a molotov cocktail in the alley is a great move, since you'll be able to hit everyone confined in such a narrow area. Follow the alley until you spill out into the main street. Clear out any Infected wandering around in front of you, then hug the right wall to find an open door.

Enter the building and explore inside. There is a first-aid station in the first room on the left, where you can find either pain pills or a first-aid pack. Also check the other rooms for weapons or Infected.

There are two ways you can go from the streets. Of course, you can follow the street to your main destination, which seems like the obvious choice. If you want to branch off a little bit, head towards the eighteen-wheeler parked next to the metal fence.

Sneak between the truck and the fence to find a warehouse. Go inside; there are usually pain pills or hand-tossed weapons on top of some Infected. Going through the warehouse will eventually take you to the opposite side of the street. The choice is yours. I mean, it's not really that long of a path and you can easily take both. Small level. =/

There is a red car in front of the subway entrance that still have an active alarm system. As one of the survivors points out, don't set it off. If anyone touches or shoots it (even an Infected), the alarm will go off and attract the Horde. If you're playing smart, avoid it like the plague. If you are like me and want to have some fun, sound the alarm and deal with oncoming rush.

The safe house is right down the subway stairs. The path leading to it is usually safe, so you should have no trouble getting there. In fact, I like to sound the car alarm and get the Horde after me, then bolt down into the safe room. Once everyone is inside the safe house, close the door to end the level.

THE SUBWAY

Safe houses are filled with ammo, weapons, and other useful items. Stock up on ammo and items and switch out your main weapon if desired. Look through the door leading to the subway and pick off any nearby Infected through the hole.

Open the door up and shoot any Infected here and the floor below. Make sure not to fall down the hole. Like the hole in the apartments, try to pick off any visible Infected before actually dropping down and sealing your chances of returning shut. Waste as much ammo as you want, because you can always walk back into the safe house and grab more ammo.

Fall down into the hole and clear anyone else out of the area. A Smoker will most likely make his appearance above you, so listen for his trademark snarls and keep an eye on the scaffolding above.

Enter the small corridor to the right of the stairs, where items are usually found. You can also drop down into an air duct, for whatever reason. You can use it for protection or to simply hide yourself from the Horde if they happen to appear.

Either go down the stairs or through the air duct to reach the Holly Street station. Take down the Infected here (there's usually a nice amount) and scrounge the area; items are sometimes held in the small booths on either side of the room.

Tip: Tables

There is a table here that will occasionally hold an ammo stash or upgraded weapons. This is another situation where the AI Director will get the best of
