Many Glitches Now Fixed For Left4Dead

Many of you , myself included , should be happy to know many of the
glitches in L4D have been patched very recently. I noticed upon start
of my 360 yesterday , that an update was available. Since I play
nightly on line I knew it was a brand new update and possibly would
fix many of the glitches. Upon start of Dead Air, I first tested the
chain-link fence glitch which allows you to hop on top of the fence
and run to the end of it and jump across onto the electrical box and
hop up to the other building and avoid the horde by not alerting them
via the crane.When I jumped there's NOW an invisible barrier
preventing you from jumping across the other side. Also just past this
area you can (walk down) off the building and fall into a tree and go
straight to the save house on the street below. Now when I tried it
wouldn't let me do it, it causes you to go into a falling off the
ledge bleed out , only a team mate can save you at this point. I also
tried the famous Mini-Gun glitch at Dead Air's finale and it's fixed ,
no longer can you power up the mini-gun by melee'ing it , and no
longer can you jump up to the plane's wing. Also they fixed the glitch
in the construction yard where you can hop off the white railing onto
the ledge above the metal doors and then run and hop over the wooden
barrier that needs to be burned which in turn alerts a horde. YOU CAN
still jump up there. but as soon as you do , you can't move more than
an inch, there's now an invisible barrier blocking you from jumping
over the wooden barrier.

One thing they didn't fix yet is the Jesus Room on No Mercy finale,
that glitch was still working tonight/today.

I'm off to test the other glitches to see if they're all fixed , like
the (2) rocks in Death Toll's boathouse finale and some others.

I'm sure all of the mini-gun glitches are fixed, I was surprised to
still see the 'Jesus' Room up and glichable. Seems like the easiest
fix of all the glitches and I thought for sure would be the very first
glitch to be fixed.

Anyways, this also must mean that there's some fresh DLC just around
the corner, for the best co-op game in the world, ok maybe not the
world, at least my world. heh.

Hurry up though I'm getting bored of the same ol' maps Valve!
