Left 4 Dead was originally being done by Turtle Rock Studios (notable for doing several things for VALVe, such as CS:CZ, Some maps in CS:S and the Xbox port of Counter-Strike), until VALVe bought them up sometime around 2008. At this point, the game looked very different to what we have now.

Yes, this game looked very different. Surprisingly, the level design/gameplay never really seemed to change.
Now, with L4D using a different file system, you’re going to need to update GCFScape. The game taunts you by storing all the simple stuff in what is a normal source game directory, not a GCF. But, the materials and models are all stored in VPK files, notably pak01_dir.vpk. A quick disclaimer is that most of these images are fused together to make it easier on me. Again, let’s start of with something that is incredibly expected.

Found in the VPK under “materials/console”
This was so predictable it was not funny. Along with this, under “materials/gfx/vgui”, is a ridiculous amount of Counter-Strike stuff. For those who do not know, L4D results from a Counter-Strike Source mod known as “Terror-Strike”. Seems obvious this would be left in.

Found in the VPK under “materials/console”
You know how most VALVe games has the level on the startup, and it starts blurred? To achieve that effect, the blurred images are created and stored as normal images. These seem to be hints of early levels or something. But even better is…
Found in the VPK under “materials/console”
If you can’t tell what this is, you can click it. And if you can’t tell what it is then, you need glasses. These are what appear to be very early finales for “No Mercy, Dead Air, Death Toll and Blood Harvest.”
Found in the VPK under “materials/console”
You all should have seen this before. Screamer blah blah blah. Moving on.
Found in the VPK under “materials/resource”
Oh, silly VALVe face.

Found in the VPK under “materials/vgui/tools”
I think putting the Filmmaker is pretty taunting of them. That was supposed to be released with TF2. Actbusy made me laugh though.
That’s about it. I may or may not possibly do a second part when the SDK finally comes out, as viewing the models right now is not fun.
