(adsbygoogle = window.adsbygoogle || []).push({}); so tekkit is a multiplayer server mod that is self downloading and actually is several mods smashed into one giving you more ores, objects, terrian (including the ocaccasional volcano) and presents a new concept to mincraft a minimap. this mod is also available in singleplayer under the name of technic. i personally love this mod as it raps most everything you could ever want from minecraft into a small package. it throws minecraft ahead centuries with motors powertools and nuclear power. i could never explain all that comes with this minecraft extra so try it for yourself!
