Left4Dead servers went live on November 19, meaning that if you’re even here reading this you have a very poor grasp of priorities. Â But we’ll make it worth your while with some tactical advice that might just keep you and your fellow survivors alive come Finale time.
1. Â The Pistol
Years of first person shooter experience have trained you to believe that the pistol is puny. Â It’s something you know as deeply as your ABCs and now, thanks to Valve, it’s wrong. Â The pistol (or better, pistols) are a real force to be reckoned with and their proper use will do more for you than any of the larger weapons.

They’re powerful.  They’re accurate.  If you’re close enough you can drop regular zombies with a single headshot, so you have to resist the action movie urge to empty clips into each body (an especially powerful feeling when you’re all Chow Yun Fat-ed up with twin pistols). Use your pistols whenever you can - especially on Expert, when you’re going to need to conserve your heavy weapon ammunition for the real emergencies.
2. Â Shotgun/Combat Shotgun
Booyah!
Oh yeah, that shotgun feels GOOD, doesn’t it? Â When the evil undead come screaming at you there’s nothing quite like reminding them why “the ability to use tools” is such a powerful advantage. Â Especially when those “tools” can project cones of lead shot which mince anything in front of you.
That “cone” thing is important: if you can see any teammates, you are not using the shotgun properly. Â Get out in front and stay there, crouching so that teammates with the more accurate machine gun options can sharpshoot over your shoulder. Â Oh, and a message from everyone you’ve ever played with on an L4D server: DO NOT KNOCK HUNTERS OFF WITH THE SHOTGUN. THAT HURTS. A LOT.
3. Â Uzi/Assault Rifle
Point 1: Â The automatic weapons can rapidly pump entire clips into approaching foes
Point 2: Â Do not pump entire clips into an approaching foe.
No matter how desperate things get, aim for the head
The fully-automatic fire can obliterate the infected and then, when you’re out of ammunition, the infected can obliterate you. Â Restrain yourself to burst-fire, popping off heads as you run for the safe rooms and saving the full-clip head-height sustained fire for the inevitable Horde-ings.
4. Â Hunting rifle
This bit is almost relaxing
An absolute joy.  Setting up camp and popping heads from a safe distance is one of the greatest pleasures in the game, and if it wasn’t for how the Director will kill your ass then everyone would do it.  The problem is that the Director, the software that controls zombie distribution, can get bored.  And you don’t want that. Anything that can trigger Hordes and Tanks on you is not something you want to bore, trust us.
The key to proper hunting rifle use is prioritising targets: stop, pick off as many infected on your intended route as you can in a few seconds, then move on. Â There’s also the Highlander effect: there can only be one. Â More than one hunting rifle in a group and you might as well be waving candyfloss at the inevitable Horde.
5. Â Doors
You might not automatically think of doors as weapons. Â This is because you’re not a paranoid schizophrenic. Â But if Valve offer you a device which can detect zombies and freeze an entire Horde while letting you shoot at them you’d be a fool to turn it down, right?
What we’re saying is “Close the doors behind you!” Â Just like your mother did, but it’s considerably more fun this way.
