Left 4 Dead
Invincibility while reloading:
------------------------------
Press B to reload, then hold LT to knock back attacking zombies while reloading
your gun.
Fast melee:
-----------
When using melee (LT), press Y, LT repeatedly. You will switch weapons and
melee. This helps to complete the game on the Expert difficulty from hordes of
attacking zombies.
Easy kills as Infected in No Mercy, Level 3:
--------------------------------------------
The Survivors must jump into a sewer hole at a certain point. As an Infected,
use this to your advantage. While playing as a Smoker or Hunter, hide behind one
of the large canisters in the room. Once one of the Survivors open the hole and
are done checking the vicinity, they will jump in. Due to the fact they must
jump in one at a time or get stuck, make sure you have a clear view of the last
one in line. Once all three are down and the fourth Survivor is still up, pounce
or grab him or her. By doing this, he or she will not be able to be saved,
unless someone throws a Molotov cocktail or pipe bomb.
Easy wins as Infected in No Mercy, Level 3:
-------------------------------------------
This trick works best as a Hunter. Before you spawn in the No Mercy campaign,
Level 3, go all the way to the very end, at the hospital. Once up the ladder,
turn to your right, and there should be a dumpster. Move it all the way over to
the manhole, and one of two things will happen. It will either fall all the way
down, which is bad because the Survivors can't move it; or it will partially
fall in. The survivors cannot move this at all. If you are a Tank, you can move
a car over it, which is better than the dumpster. From here, do not puke on them
as a Boomer, as it will attract the Horde. The Horde will try to move the object
away from the manhole. Then, attack them as Hunters and Smokers. They may shoot
you, but every so often, you can hurt them until finally they die.
Easy wins as Infected in No Mercy, Level 4:
-------------------------------------------
Before you spawn, go all the way up to floor 28, where the elevator lets out.
Just outside of the elevator is a generator. Move it in front of the elevator
door. If the Survivors know what you are doing, they can move it. It requires
three survivors to move an object. However, if you have someone else on the
Infected side, they can go a little bit further and move the forklift in front
of the doorway.
Easy "Cr0wnd" achievement:
--------------------------
Play on the Easy difficulty. Get a shotgun, and find a Witch. Quickly approach
the Witch with your flashlight off. As she rises, quickly shoot her in the head
to kill her and get the "Cr0wnd" achievement.
Easy "Helping Hand" achievement:
--------------------------------
While in a safe house, preferably one with a combat shotgun, incapacitate the
other three members of your group, then revive them. Doing this counts toward
your achievement. It is easier with a combat shotgun because it deals a lot of
damage fast. In a single player campaign, make sure all other survivors are in
the lower red health area. When you incapacitate one of them, the others will
try to revive them. You then need to shoot the others before they revive the
incapacitated players or you will not get the points for reviving.
Easy "Unbreakable" achievement:
-------------------------------
If you have a health pack and are low on health, pause the game, and select
"Take A Break". While you are idle, you will be healed. Once you are healed,
rejoin the game, and the healing will not count against you. Note: This was
done on the Easy difficulty.

Tips:
-----
Submitted by: XxXPRODIGYXxxX
on the second chapter or dead air you will need to alert the horde by lowering a crate using
the crane you can skip this without teleporting or any hard to do glitches when facing the crane
walk right and where the crate will be lowered. On the left side of the builing that you have to
get across to there will be a telephone/power box jump on to it and you should hang then get a
team mate to pull you up and you will be on the building without using the crane and alerting the
horde (valve has taken the power box out of verses mode)
Mini Gun Launcher:
------------------
Submitted by: man
First find any minigun then hit it using LT. The more you hit it the more powerful it gets.
Remember :you can hit it as many times as you like. Once you don't want to melee it anymore you
can jump on it then it will launch you more push you out of the map.
Stronger Hunter:
----------------
When Hunters are on fire, their pounces and attacks on Survivors do more damage per hit. Use this
to your advantage, and deliberately set yourself on fire with fire pits or burning cars, then attack.
This allows you to easily down Survivors. Note: This only works for Hunters, not Smokers, Boomers,
or Tanks.
Defeating Tanks:
----------------
To kill a Tank faster, throw a Molotov cocktail, or a gas tank and shoot it. When the Tank is on
fire, shoot him with an assault rifle.
Defeating Witches:
------------------
To kill a Witch faster, throw a Molotov cocktail. When the Witch is on fire, shoot her with an
automatic shotgun.
Shortcut in No Mercy: The Apartments:
-------------------------------------
As soon as the level starts, look over the edge of the building and down to the street. Notice
the box-like object that is partway down. Drop down to it. Although you will take some damage,
you will still be alive. You can then drop down to the ground and continue the level.
