Enjoy!

P.S. Actually I made this mutation to practise against real players and earn more experience/skill.

Don't let these sonsabitches get their bloody hands on ya, 2-3 hits will knock you down. These bastards are tough, the only way they die is by removing the head or destroying the brain. There are no special infected or bosses, only scripted tanks and tanks at the finale. always watch your back, they are slow but they can sneak up on you. If your buddy gets swarmed and you are surrounded...he's dead. but its not that hard to get head shots if you take time to aim.
There isn't a rush so search everything, but make sure there are at least 2 exit because you could be trapped.

Some players may decide to "opt-out." (ragequit)

This mod changes the entire feel of L4D2. It is meant to take away the arcade-ish feel of the game and feature a much more realistic, REAL APOCALYPSE feeling.

Also includes a solo version if this mod, a mutation which you can play without bots.

PLEASE READ THE DESCRIPTION IN THE CHANGELOG BY CLICKING THE CHANGELOG LOGO IN THE PICTURE.

It is a long description but it's important if you want to play this!

Have fun!

which serves to transform a standard tank in a shooter supertank explosive rocks, and thus make the game much more difficult.

Gives all maps(even customs) a very dark atmosphere, also adds more pills/defibs, as well as instant kill witches, anything that has to do with zombies and SI has been left alone.

For those of you that had the Ultra Realism VPK, dont forget to delete it. :)

There 2 Editions now, the Darkness Falls Gamemode keeps the HUDs while the Darkness Falls SE Edition disables ALL HUD's, including chat.

You WILL have to disable any addons that adds menu items...once you install the addon the Darkness Falls mutation will be able to be selected from the main menu.

Fixes the "Dead Air" and "Blood Harvest" campaigns so common infected do not attack the player during certain crescendos in the Mutation: Last Man On Earth. May also fix unwanted crescendos in Community Campaigns.

NOTE: Other Mutation/Game Mode related add-ons may clash with this one. Please disable clashing add-ons when using this.

Minor paranoia due to flashbacks of the tragic times had on LMOE prior to this add-on are common. That is to say, if you hear Common Infected but never see them, it is totally you going crazy, and not the fact that this fix simply makes it so common infected cannot move (and therefore 90% of the time will quickly despawn due to not being able to reach you).

Bringing it on par with Rayman's latest version.

Adds a lot of Custom Mutations created by me and others.

The main-menu has been edited so all Mutations can be created via lobbies, and can be played online at anytime. To play Custom Mutations online, they'll have to be played via a Local Server.

If you don't like the default look of the main-menu, you can try out Urik's Game Menu that contains my Mutation Mod found in the link below as a separate mod.

Final Battle mutation (solo survival) is just a quick gamemode made by me.
I think this might've been created already , but i made this one myself anyways.

Mainly created for myself...

You play survival all alone against zombies , boomers , spitters and tanks.
Special infected that pin down enemys have been removed , but zombies does now do double the damage.
Tanks have 2000 health.

You can start this mutation from the mutation button in the main menu. Please note that if you already have a mutation installed that uses the mutation button that it might conflict then.

Known bugs are in the changelog,
Have fun!

Samurai's Apocalypse Mutation features singleplayer gamemode , with only 1 survivor and only having a katana against thousands of zombies.

PLEASE BE AWARE , YOU CANNOT PLAY THIS MUTATION ON A CAMPAIGN/LEVEL THAT DOES NOT ALLOW THE KATANA WEAPON (such as the parish, swamp fever,...)
I made a fix for that , but that caused to break the entire mutation mod.
full information in changelog.

Only the following infected are enabled;
Common zombies (also uncommon zombies)
Boomers
Spitter
Witches

Other Information:
This is my first Mutation , this was very difficult to create and was mainly ment for myself and friends.

see the changelog
how to play:

A survival mutation. You are given baseball bats, adrenaline, and healing items. Only Chargers and the occasional Tanks spawn. Your goal: Level as many Chargers as you can, before they get a chance to level you. The Charger cap has been raised to 15.

Place the batter up.vpk in your addon folder, and make sure there are no other .vpk files in the folder to avoid conflict.

To play the mutation, open up the console and put in (without the "") "map [map] offisir1"
[map] is whichever map you want to play on.

The Walkers mutations are inspired by such films, shows, and games as Dawn of the Dead, The Walking Dead, and the early Resident Evil series. The aim of Walkers is to have classic shambling zombies while keeping the game fun and challenging. Walkers adds two mutations that replace the Special Delivery and Flu Season mutations.

I may be making further changes as feedback comes in.

For game mode specifics please see changelog.

A modification to the Classic mutation. This time you're on your own. You get melee weapons, pump-shotguns, hunting rifles, molotovs/pipe bombs/boomer bile, and healing items. There are no Special Infected, but there's double the common infected.

Place the lone survivor.vpk in your addon folder, and make sure there are no other .vpk files in the folder to avoid conflict.

To play the mutation, open up the console and put in (without the "") "map [map] lonesurvivor"
[map] is whichever map you want to play on.

Back to the good ol' days. Hunting zombies with shotguns, blunt and homemade objects you would find in your garage. Only common infected spawn, and they hit much harder. The only weapons are pistols, pump shotguns, molotovs, pipe bombs, melee weapons and chainsaws. You start with a shotgun, baseball bat, and some pain pills.

Place the classic.vpk in your addon folder, and make sure there are no other .vpk files in the folder to avoid conflict.

To play the mutation, open up the console and put in (without the "") "map [map] classic"
