Kovacic's Mod Pack (KMP) is made for those who need a simple and painless Minecraft Mod installer. Skip the complicated launchers! KMP was designed in Southern California, USA, with simplicity in mind. It has over 30 mods, maps, and texture packs to choose from. Installs Minecraft mods in less than 2 minutes after downloading (seriously, start a timer). Over 2 million downloads can't be wrong. Best part is, the packs are absolutely free.
