Omega – the largest DLC to hit any Mass Effect game – is now available for purchase and download on Xbox Live, PSN North America and Origin. PSN Europe will get the DLC tomorrow, November 28.

In this new chapter in Commander Shepard’s adventures, players will return to the seedy space station Omega and fight alongside Aria T’Loak to liberate it from Cerberus hands.

Cerberus agent Oleg Petrovsky and his squadron have seized the infamous black market trade post known as Omega. As its self-proclaimed rightful leader, the legendary biotic Aria T’Loak plots her revenge to reclaim her domain by teaming up with Commander Shepard and another mysterious ally. They must put aside their differences and fight side-by-side to defeat the Illusive Man’s reign over the space station and free the enslaved people of Omega.

The launch trailer will give you a better understanding of what’s expecting Shep and his gang on Omega.
