Mass Effect 3's Omega DLC is now available on Xbox Live.
The DLC sees Shepard teaming up with the pirate queen of Omega Aria T'loak. The duo are joined by a new female Turian character and embark on a mission to seize control of Omega from Cerberus' General Petrovsky.
Michael Gamble, producer on the Mass Effect franchise at BioWare, described Omega as "double the size of the largest DLC" the studio has done for Mass Effect 3. You can download it from Xbox.com for 1,200 MSP.
BioWare Montreal has said Mass Effect 4 will be powered by DICE's Frostbite engine and enhanced by systems built for Dragon Age 3.
