While the Live-Action web series based off the Dragon Age series, staring Felicia Day (Dr.Horrible, The Guild) as the Elf assassin Tallis had been pushed back to October, it seems due to a marketing ploy, as on October 11th the latest DLC for the RPG series Dragon Age 2 will be released.
The DLC, called “Mark of the Assassin” will feature Day’s Character Tallis, joining up with Hawke to steal an artifact that is guarded by soldiers, monsters, and traps. Bioware released a trailer, however didn’t disclose any price for the new DLC or any extra information, like if Tallis will join your group after the mission.
