Ballistics expert Professor Anna Wrack reveals all. My colleagues and I are pleased to announce the fruition of our latest project, the creation of a ballistic ship-mounted weapon. Known as the Mass Ion cannon, it functions round the principle of projecting positively-charged microparticles of depleted Plutonium at high velocities. It's effect on shields and armour is comparable to an average Medium Laser; however, it ahs a marked advantage over all beam weapons in that heat build-up, the Laser's greatest curse, is completley absent. This permits an extremely rapid rate of fire to be maintained for long periods of time, allowing a skilled pilot to destroy enemies very swiftly.
