Hack/Mine Client and Server
Hack/Mine is a RPG-like modification currently for Minecraft 1.2 and is included in the Technic launcher. If you are able to play on Lowe’s, you can also try Hack/Mine by selecting the mod from the launcher dialog.
There are 3 classes to choose from including Mage, Warrior and Ranger.
And you can play as a Steve, Dwarf, Elf or Halfling. The items magical properties remind me of Diablo.
In Hack/Mine the monster and dungeon difficulty scale as you move away from spawn. There are towers, boss monsters and accessories such as jewelry as well as magic weapons such as staves.
If you want to try this out, connect the Technic pack’s Hack/Mine client to port 12345 on the regular server. Get the Technic launcher at http://www.technicpack.net/
