Star Trek Online: Legacy of Romulus? Get in line behind pretty much every single STO player, pal. But while your specific query may not reach the ears of top admirals, Executive Producer Daniel Stahl created a special edition of Ask Cryptic devoted to answering the most common questions out there.
So what's included with the Romulan faction? Stahl says that there are three races (one free, one unlockable or purchasable, and one for subscribers only), adding, "The Romulan Republic was created from the ground up as a complete new faction. They have their own backstory, their own exclusive missions and episode series, exclusive costumes, faction-exclusive social hub, unique playable species, a full ship progression line from level 1 to 50, unique HUD UI, and more."
While Romulans will be an independent faction, Stahl explained that these captains will choose to ally with either the Federation or Klingons for the purposes of storylines, PvP, and starbases.
