Heavy Gauss Cannon
The Heavy Gauss Cannon is a weapon used primarily by the Necrons, by the Necron Heavy Destroyer. It is part of the Gauss Weaponry list. It is a larger version of the Gauss Cannon, although it only has one barrel and so a slow rate of fire. Though it has the greatest power, and as such range, its reduced rate of fire makes it less effective against vast armies, but more effective against certain heavily armoured targets, such as Land Raiders.
