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.
