Each of the downloads contains instructions on how to install the mod and addons as well as pictures of the addons except the no hats one because its obvious what it does...;) So basically it does what the title says. In the past I had mediafire links but no one used them so now I uploaded them to the site because it worked this time. There is plenty of screenshots to show it in effect and the addons show what they do in the addon icon. So have fun.
Ok so if someone else also installs the mod and your chosen addons they can also play with you in the multi, it works! HOWEVER the no hats addon causes multiplayer to crash and I do not know why.
