Left 4 Duke 1.5b

Left 4 Duke is a compilation of the Left 4 Dead addons I use, along with some custom changes:

New scripts, weapon models and animations from various artists on l4dmaps.com (Credits for those files: A1/AC/anabsoluteblast/arby26/dani1341/Doktor Haus/Fauckers/Ghost/Grimlock/HyperMetal/Ippe/K1CHWA/KillznThrillz/Kimono/l0rdn00b/Lurch/miztaegg/modderfreak/MTK/PappasKurtz/Pete/Praetor/R.T.Frisk/SoulSlayer/Spezz/splinks/Sproily/SteamPump/Stoke/Thanez/The Real Ellis/tigg/TwinkeMasta/Unclerage/Xenecrite).
New weapon sounds mixed and matched from the most realistic sounds from the sound packs released by Mateoski and EllistheMechanic.
Heavier gun recoil and modified magazine capacities to be more realistic (17 round G17 mags for the G19's, 30 round mags for the rifles, 6 round capacity for the magnum revolver)
The ability to crawl and shoot (but not at the same time) while incapacitated.
Improved bot behavior. Bots are more aggressive at staying ahead of the players, and are more enthusiastic about headbutting witches (so you don't have to).
Infected act more like classic "shambler" zombies, and are tougher. Only head shots can quickly take them down.

Version changes:

1.5b OK, fixed the ghost gas can bug for sure this time. Hopefully. Also wrote a program to wrap the vpatch in, for more reliable patching than with the batch files.
1.5 Chainsaw fuel increased. New m60 and m79 textures. New sound for the m60. Two additional reloads with the m60 (but still cannot replenish from ammo pile). Limited handgun ammunition (120 rounds - unable to display reserve ammo on UI due to game limitations) and increased its mag to 200 rounds. Reduced shoving penalty. Rebuilt audio cache again. Hopefully fixed the ghost gas can bug.
1.4 Shambler zombies nerfed by 50%. Survivor bots more accurate and maneuver better. Tanks will be far more unlikely to suicide if they cannot reach a player. New models for the crowbar, guitar, axe, machete and katana. Removed new ellis skin in preparation for new survivor skins. Rebuilt audio cache.
1.3 New models and sounds for both sniper rifles and a new model for the semi-auto shotgun and AK-47. Improved survivor eyeball models by AC. Infected take less damage from non-head shots and behave and spawn differently. Increased gun recoil. Added UI icon for the Magnum Revolver.
1.2 Changed MP5 and shotgun sounds, and a few changes to bots. Added ability to crawl while incapped. Implemented custom sound cache to fix audio glitches.
1.1 Added new weapon sounds and bot improvements.
