Legacy of Romulus
 New character
- Instead of having to play a Federation character to level 20 to unlock the creation of a Klingon Empire character, every faction, including the new Romulan Republic, will be playable from the beginning of the game.
 Playable Romulan Faction
- A new playable faction, the Romulan Republic, became available to players with this expansion.
- The player can choose between Romulan and Reman playable species for this faction.
- Remans will be available as either a C-store unlock, or an account-wide reward for achieving Tier 5 in the Romulan Reputation System.
- Around level 10, in the mission “Turning Point”, players will have to ally with either the Federation or the Klingon Empire.
- This choice is permanent, and will allow access to some of the ally's equipment and starships.
- Empress Sela and Colonel Hakeev return in the story, including voice-overs by Denise Crosby.
In addition to their ally's Tier 1-4 ships, Romulan players will be able to fly iconic Romulan warbird class starships. These ships use Singularity Core engines, and cannot equip standard Warp Core engines.
