Alien Swarm Classic Challenge

A challenge that re-enables and changes a number of gameplay elements in an attempt to recreate the feeling of the UT2k4 version of the game, as well as a touch of Alien Swarm:Infested.

A list of non-Cvar changes can be found below:
+Officer class renamed to Explosives.
+The Rifle, Prifle, Shotgun, Vindicator, Flamer, Autogun, Grenade Launcher, Sentry, Sniper Rifle, and PDWs are the only available weapons, with a few previously hidden weapons being unlocked as well.
+The Flares, Welder, Medkit, Incendiary Mines, Stims, Flashlight, Night Vision Goggles, Grenades, Freeze Grenades, Gas Grenades, and Laser Mines are the only available items, with a few previously hidden items being unlocked as well.
+The ammo bag replaces the ammo satchel, fit with ammo for nearly every weapon. AI marines know how to resupply allies and, if the carrier is damaged by enough fire, the bag will explode. This is usually fatal to himself and nearby beings.
+The medical satchel replaces the heal beacon and heal gun. It is an individual healing item, only having the ability to heal one person at a time. Medics with points in healing get more of them. Use them wisely.
+The Grenade Launcher and Laser Mines are now restricted to the Officer, or Explosives, class.
+The pistol and the deagle are now both an offhand item that you can take into the field. AI marines can also switch to them if they have no available primary or secondary weapons.
+The deagle has been restricted to the medic.
+The T75 bomb is now an available offhand item for the explosives class.
+The 50 Cal Machinegun has been re-enabled and is available only to the Special Weapons class.
+The descriptions and names for the marines, weapons, and items have been changed to their UT2k4 counterparts.
+Weapon clip sizes are now balanced to their original values in AS:UT2k4
+Drones no longer glow in the dark and use a darker skin that is more comparable to UT2k4 and Infested

Note: There are mods being used in the screenshots that are *NOT* included in this challenge. Visit the above collection named "Alien Swarm Beta Collection" to find them.
Note x2: This was primarily tested on the Jacob's Rest campaign and had little to no thought in mind for any other campaign. Keep that in mind.
Note x3: Playtesting was also only restricted to four marines on Normal and Hard difficulty in singleplayer. Below and above that might field drasticly different results.
Note x4: This mod includes a number of files that run *outside* of the challenge. That means that they will change things even if you aren't actively playing the challenge itself. It's recommended that you disable the mod in your addons list before going back to play any other gamemodes.
Note x5: Level requirements assume that the player is maxxed out in experience, hence the order of weapons being different.
