The Hack/Mine Modpack is a modpack available in the Minecraft Technic Pack Launcher, which also houses the Yogbox, Tekkit and Voltz. It gives you the ability to choose a race. Either an elf (which makes your character taller), a dwarf (which makes you shorter), a wizard (which gives you magic), or a human (which you remain the same). Each race has their own special perks and abilities. It adds different biomes, new mobs, new places to discover. It makes Minecraft a more RPG-like game.
Simon, Lewis, Duncan and Martyn have all played with this mod. Simon, Duncan and Lewis have 6 episodes covering it (3 playthrough episodes, and 3 update episodes), while Martyn has 5 episodes (all playthrough).
