Introduction
Rayman1103's collection of mutation mods is amazing, but it offers no explanation as to what each mutation actually does. Although there exist a few annotations on the internet, the ones I found were not user-friendly at all, so I took the liberty to create this list. The mutations are categorized in the same way as they are in the game. If you see any mistakes, feel free to correct them in the comments below.

Note: Throughout the guide, you may see the term Leaker pop up. If you are unaware, Leakers were a type of Special Infected that was eventually cut from the final game, and were a cross between Spitters and Boomers. They would rush the player and explode, causing the ground to catch fire. Both the explosion and fire would deal damage to the player.

@King Link it is at the battom and also, you don't go on the guides looking for a mod
King Link 16 Jun, 2017 @ 11:54pm 
Just a thought...

Maybe a link to his mutation list at the top of the guide, I didn't understand what this guide was until I really thought about it. Maybe I'm slow (maybe I'm just trying to read while playing) but it'd be useful to say "go here, this is an explination of all the mutations in this pack)
