Left 4 Dead Hints

First so u all no, everything is random(almost), however hav everyone attack from a distance after u contact the help.

NOTE: U might want to aim good, use sniper, and never split up, oh and try to find places where they can't reach u.

First, go to ur pistols and press and hold Y and melee, let go of Y and imediatly press (FIRE), wait 5 secs and let go of melle and it should shoot really fast! it will do the same amount of damage as if u shot a whole round except its REALLY fast!

1st u can't get a rocket launcher, 2nd when a witch gets up straight away shoot her head with shotgun, use this to get the achievement.

When a hunter in SEWERS b4 they all go in pounce on the 4th person after 3 hav gone in.They can't get to u now.

in chapter 1 lv1 as a smoker go on the building where u can c da car with the alarm,hope u hav good team mates to slow them all down at this point so u can easily constrict the enemy, works for the smoker achievement.

when some one is being destroyed by Normy infecteds, attack them as any infected and if you die ur team and regs will destroy e'm, repeat this a lot to win.

as a survivor pick the shotguns and stay very far away from infecteds, only gun u need.

If u use any gun u want ( for ones where u hav a horde i recommend machine gun) you should win easy

for the use pistols only achievement, grab a 2nd one and use pain pills and use medy packs for easy win win win!!!

Door pwnage 1: When a Zombie chases you into a room close the door when it is near the entrance. It wil launch the zombie backwards and probably kill it.

Door pwnage 2: Sometimes when killing a zombie through the grated bars of a Safe Room Exit. You will see it's arms dangling from the bars. If you are looking for fun then repeatedly whack it and it will swing back and forth, back and forth.... XD

P.S No doors were harmed during the makings of these Pwnages... LOL XD XD XD

On the finale of dead air clear all zombies do not alert horde till you do this..... go to the turret and bud wack it for 5-10 minutes it should be bouncy go to the side were you can see the plane wing then aim for it then jump on the turret if you jump in the rong spot u will die or be downed (incapated) this glitch is good because only smokers can reach u so stand in da middle of da plane then kepp hitting and spinning. the glitch happens oon the saftey plane so grab a pipe bom throw it when ya get down to get in and run!!!!!!!!!!! have fun my gamer tag is hillbbilliee so send me a friend request and we will play some time.

When u shut tho safe room door if only 2, or 1 other person is wif u or ur by ur self shoot thru the tiny eye hole neer the top of da door.
