Oh, they'll take the demo down when the game comes out you know, sucks to be you. And Valve delayed it again, now I have to wait till 2000.
EDIT: I was messing around with the files for it, I found a list of all the weapons in the demo.
Some poking around in the text files (all the models and skins are encyrpted) and I found this; "L4D2_Instructor_explain_stage_finale_start" "Begin the rock concert to signal the chopper"
some of the dialogue is pretty funny too;
"Gambler_BoomerJar04" "<clr:64,100,166>Nick: Grabbin' puke!"
"Gambler_BoomerJar05" "<clr:64,100,166>Nick: ... for some reason."
"Mechanic_FriendlyFire16""<clr:223,200,143>Ell is: I'm gettin' so mad I could shit a squealin' worm."
"Coach_EllisInterrupt09""<clr:112,75,125>Coach : I'm listening. But this better be about pancakes."
"Coach_EllisInterrupt10""<clr:112,75,125>Coach : All right, you MENTIONED pancakes, but it wasn't really ABOUT them, was it?"
"Gambler_HeardWitch03""<clr:64,100,166>Nick: I think I hear my ex-wife..."
"Coach_IncendAmmo02" "<clr:112,75,125>Coach: Grabbin' fire bullets!"
"Coach_GettingRevived13" "<clr:112,75,125>Coach: They better name a school after me for this shit."
"Mechanic_GrabbedByJockey07" "<clr:223,200,143>Ellis: IS THIS THING HUMPING ME?!"
