Gatling-style Bus Cannon
The cannon that LEGO put on the Paranormal Intercept Bus 3000 is cool, but it's very blocky and looks like it would be a "pulse cannon" that doesn't look like it has a fast rate of fire. I thought about mounting a Brickarms cannon on top instead, but that would spoil the "ghost hunter" look. So here's a Gatling-style or minigun-style gun that looks like it has a crazy fast rate of fire to take down swarms of ghosts. Note: this cannon won't work with with the app, I mean, the app will still recognize the bus, but it won't be able to detect the cannon. Also, this is not built with parts from the old cannon.
