A mutation that attempts to recreate the Left 4 Dead Beta experience, mostly using cvars. A list of changes are below:
+Only Boomer, Smoker, Hunter, Tank, and Witch spawns
+L4D1 weapons/items only
+Shotgun and Autoshotgun max ammo has been increased to 128
+SMG max ammo has been increased to 480
+Pistol max ammo has been set to 240 (Works but there’s no way to know ammo count)
+Female Boomers never spawn
+No cooldown/fatigue from pushing
+Friendly Fire through walls
+Glow on far away items have been disabled
+Crosshair colour has been changed to green
+The Director attempts to always spawn wanderers
+Death notices for bots have been disabled
+No more floating names above players
+Pipe bomb timer has been reduced to 1
+Survivor crawling
+Smokers can voluntarily release a survivor (Tested, works!)
+Smoker tongue drag speed has been drastically increased
+Tank health has been increased to 9000 (Better bring molotovs!)
+To make up for not being able to figure out how to make the witch incapacitate all survivors when startled, she instantly kills the one that does it making her a threat anyways.
+Tanks do not slow when shooting them.
+Boomers use cut leaker behavior instead of normal behavior (as I wanted them to deal damage on death, this was the next best thing)
+Bots friendly fire
+Players ragdoll on death
+Left 4 Dead 1 population restored
(disabled right now) Players unable to walk through each other, fit with unused voice lines! Suggested by Gyroic
+Tanks no longer shake the entire screen when they're around
+Red light on witch has been removed
+Cinematic lights on pinned survivors has been removed
+Some cvars are rebalanced to l4d1 stats, such as the minigun and tank fire damage
+White glows around survivors instead of green (featured in some beta footage)


File names:
"beta" for coop
"betav" for versus mode
To access these mutations via console type: "map mapname beta" or "map mapname betav"

I highly recommend an improved bot mod to reduce the chances of them getting stuck/friendly fire cases.
Note that some screenshots are outdated and must be replaced.

Where do you put the "beta.vpk" file?

Sorry for the late reply (I don't get notifications from ModDB for some reason) but you need to place the vpk file into your addons folder. It should look something like this:

C:\Program Files (x86)\Steam\steamapps\common\Left 4 Dead 2\left4dead2\addons
