The MAC-assisted Driller. (Magnetically Accelerated Cannon, for those illiterates out there with no Halo/practical experience. Basically a super-sized railgun.) Capable of firing a single round down a tunnel at break-neck speeds, however it can only dig through about 6 blocks deep, 3x3 square, before it breaks apart. Power required, and a single Super-alloy MAC round required. The envy of all your friends, this cannon only fires as far as Minecraft can render chunks, making it almost completely necessary to move it to continue tunnel extractions.
Idea of appearance: main entity block, 2 block "Barrel" facing one direction. cannot be rotated, can be used to blast a mob's face to kafloo-ey.
Idea for Recipe:
MMI
CCL
MMI
M = Magnet-happy item, possibly from a new machine or mineable.
I = Super-alloy, to keep the cannon from blowing itself to pieces.
C = Energy Crystal, Charged, just for funsies.
L = Lapatron Crystal, for main power storage.
C
M
C=MAC
M = Minecart
^-- possible moving platform, remotely charged by Lapo's, but only breaks through 1 layer at a time. (still 3x3)
Cannot be pushed by player off a rail.
Extra Warning: Possible risk of self-detonation from Magnetic coils so close to large power source without proper insulation.
