The mag cannon is a single-shot magnetic cannon and a very common weapon in Antarean space. Its chief role is to take out tough targets such as weapon drones and heavily armoured vehicles.
The mag cannon is designed to deliver a single shot at incredible velocity and as such it is a long-barrelled weapon, often with multiple internal rails that generate a single very powerful pulse. The ammunition is designed to defeat heavily armoured targets and release a mass-sensitised disruptor field that inverts and crushes local space. A target struck and penetrated by a mag cannon suffers massive internal damage and is unlikely to survive.
