Players who send their fleets to aid the Romulans will receive Romulan Republic Universal Tech Upgrades, which cost no Dilithium and award 15,000 Technology Points while also offering a chance to improve an item’s quality. Successfully reaching Tier 10 within the campaign will give players a new ship for use within their fleets, an Escort-style ship which boosts Engineering and Tactical values for all ships on an assignment. All characters past level 52 will be able to take part in the campaign, so get your ships ready to be deployed for the Romulan Republic once again.
