since the Tribble patch of 10 MAY 2013, ST.30.20130510a.0, can no longer see the models for the Romulan Weapons you can buy at the Flotilla. example Plasma Piercing Beam, Plasma Wide Beam, and Plasma Long Range Minigun. the only steps needed to replicate has been to equip the weapons. Attacks still happen, but no combat animations are played.
can verify for the Rifles at V and VII
can only verify for Assault at VII as at V my away team was equiped with non new Romulan weapons.
