It's simple, you mess with the trashcan you get the cannon.
Spoiler
I had two awesome games with the R63 Urbie Shotgun, maybe it's luck but it was a god damn blast, each of them. Of course I did piggy backed on some lasers. To achieve this build, I removed the Left Arm armor and left it empty for more tonnage and I also forgo DHS, for FFA as well for extra tonnage. Having those, i was able to get an XL170 with it, than the usual XL145, and then a pair of MLs as opposed of 3x SLs -- the increased range allowed it to function as a better secondary weapon, than just mere backup weapon. Of course it's pretty hot, but the LB10X is pretty cold.
