Rayman1103's Mutation Mod (Left 4 Dead 2)

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 have my Singleplayer Enabler mod (linked below), you can play 4-player Mutations in Singleplayer!

Plz Rayman help me 1.Character control isn't working when I switch to Zoey in c2m1 highway map 2.some cheats not working My Game Version is 2.2.0.1

Do you have the old version of this?. I'm playing this at 2.1.5.5 version and most of the mutation didn't work (because the addon got updated). like for example, No L4D1 Survivor spawning, No witch spawning in Witch Hunt, and something that have to do with spawning entities.

Can you double check the version you modified for me? Had a couple comments after the update. Maybe possibly still needs work.

adds more variety to an already good game!

By Trunten November 2015

This mod is essentially adding on to what Valve already started with "mutations"... adding more game modes and such. A great way to make the game more challenging without silly over modified servers or map authors abusing the director in maps.

By reidakzaktan February 2015

Pros

fun to play when you have nothing to do i like game menu graphics fun to play also with admin system works with almost custom addons campaigns

Cons

the not pausable on single player mutation ex:(one against many)

generally this addons deserve featured by valve and community. i recommended for everyone for killing zombies

By Emersonrick January 2015

Pros

- Super Interactive Menu - Dozens of varieties and ways to play - Incredibly challenging - Super useful to use as a training - He entered my favorites list

Cons

- Absolutely nothing against this piece of art.

This is perhaps the best mod mutation that played in L4D2. The huge plethora of options are incredible. Each with its characteristic, challenge and goal. I was very happy to have found this mod, he left my very best game. Congratulations and thank you for provide hours of fun. p.s.: downloaded from their facebook page

By Dumbocow May 2014

Pros

-Countless of mutations -Fun with friends -Hardcore mutation -timeless of fun

Cons

-No information for all mutation

A very fun Mutation good for everyone(not for kids) but you should add some information but Thanks for making this great mod

By vrencianz March 2014

Pros

The last duo on Earth mutations A lot of L4D2 achievements can be unlocked using the training mutations and/or the realism ones Jimmy Gibbs! It is a guideline for new coming L4D2 add-on creators Tons of other pros

Cons

Few mutations are so hard that I could not advance more than few meters from the starting safe area.

Keep your installation up to date, because - I am sure - you have this mutations mega-pack installed.
