Tekkit Classic Version 3.1.2

Throw a spear in a zombie's head! Cut a skeleton in half with your brand new halberd! Shoot some slimes in pieces with an old musket! And more!

Extending Minecraft with pipes, auto-crafting, quarries, engines and much more!

Over a dozen incredible new pipes for Buildcraft!

ccSensors collects information from machines and blocks from around the minecraft world. Those readings can be viewed on the sensor terminal or (and even better) be used in Computercraft lua programs for anything...

Add's Lua based computers to the game

This is a block that loads chunks. There is a limit on the number of chunks each non-op player can load in SMP, and each chunk loader can load an adjustable area.

EnderStorage is a mod that offers a means to store your items in The END, causing them to be everywhere and nowhere at the same time. All EnderStorage makes use of the magic of colors to link storage with its little piece of The END. Any EnderStorage with the same color code share inventory (even across dimensions). Currently there are two types of storage, EnderChest and EnderPouch.

The Equivalent Exchange mod is based around alchemy. It adds a number of extremely powerful end-game items that require large quantities of diamond to make, and large quantities of glowstone to power. It also grants the ability to easily condense materials into more valuable forms, up to diamonds and even beyond. Most of its recipes are based around the Philosopher's Stone, which you will need in order to access much of the new content.

Adds several new blocks to IC2 to make your systems more effecient.

A bench with multiple charging slots so you can charge all of your items at once. Apply redstone power to the bench to reverse the way it functions.

Combines large amounts of solar panels into single blocks turning your solar arrays into effecient small scale power houses.

Nuclear Control addon allows you to build efficient monitoring and notification system for your nuclear reactor. Also you can use Howler Alarm and Industrial Alarm in any case when you want industrial-style notification/alarming system.

Core mod required for immibis mods

This is it. IC2, the future of IC. While playing it, you will feel right at home again, rediscovering most of the stuff known from IC. However, once you get your machines running, you will quickly notice how smooth and well-designed everything works now. Wiring is easier, batterys aren't as twosided (on/off) anymore, new cables, rubber stuff, new machines, EVERYTHING was added. Create obstacle courses of Metal Poles and Rubber-Sheets, explore the Nether with an Electrical Jetpack or blow up whole landscapes at once by using the Dynamite-O-Mote. Or discover the much more complex mechanisms of Nuclear Engineering, blow up your hut or burn your hands. Or grab the rusty ol Composite Vest, and start hunting Creepers with the new, allmighty NanoSaber.

Tweaks your inventory handling to be more intuitive. Break your iron sword in the heat of battle and don't have time to replace it? No worries, if you have another one handy in your inventory it will automatically be moved into the last slot it was used! Works with all stacked items!

IronChests adds several new chests to the game. One for each type of metal. You can even upgrade them!

MAtmos is a sound atmosphere generator. When you play on any server or in singleplayer, it looks at your surroundings and generates natural noises as a soundscape, such as birds in the forest or rumbling near a lava lake or wind gusts on a hilltop, which fills out the perpetual silence of Minecraft.

Create and manipulate force fields to your will!

This is a fairly basic mod. It makes the eight 'ores' - coal, diamond, gold, iron, lapis, redstone, sopper and tin - spawn in the nether so that you have a reason to go there.

NEI is a successor to both Too Many Items and Recipe Book. It arose around the same time as Craft Guide when Alexandria and a few others on the IRC suggested that I merge both Too Many Items and Recipe Book to remove their greatest flaws, ironically too many items, or in the case of recipe book, too many recipies. Too Many Items was great, but the one thing it lacked was an easy way to search and sort your items. When you had a mod like Red Power coming along with 10000 items both TMI and Recipe Book were racking up the pages. Even if you don't want to use NEI for cheating in items, you will likely feel right at home with the Recipe component of the mod.

Easy power conversion between Buildcraft and IC2!

Have you ever wished minecarts and rails had received a bit more attention during development? Well that ends now! Gone are all those broken bits and in their place are a ton of new tools to build your massive rail system. If you ever cared about rails, you wont ever look back!

Redpower by Eloraam is a mod for minecraft which introduces redstone-like wires, cables, integrated circuits, lights, and more.

An amazing minimap display at the top right corner of the screen. Check out the thread above for a full list of all the features available with this mod.

Separate collection for keybinds

This is a small mod that adds two new blocks that I thought were missing, related to BuildCraft and RedPower. It's called TubeStuff because I don't have a better name - feel free to suggest one. The buffer could also use a less generic name.

In its simplest this is a mod that allows you to transmit your redstone state wirelessly. Even if you dont use redstone this mod could still be for you. Found an awesome landscape you'd like to mark, a cool cave to explore, or keep losing your way from base to base? Ever wished that compass pointed somewhere else or there was a way to mark things on a map. Well now there is. With the wireless addons component of this mod you can use wireless signals for navigation.
