GAC Orbital Cannon Prototype

The Gravity Acceleration Cannon is a design inspired by the MAC cannons of Halo. It builds a projectile and then uses artificial mass and gravity generators to fire it straight out. It will instantly go to the game's default max speed, and will not be very effective at low velocity, so I recommend using a speed unlocking mod (such as Bean's; links to side) to do REAL damage. Only a prototype right now, so it might not be very friendly to survival players (built and tested in creative). Also recommend using the Imperial alarm mod, but it can be changed.
