So has anyone played the Retake Omega dlc?
I just finished it and thought it was great, it wasn't as atmospheric as Leviathan was, but still very good.
It took me around ~2.5 hours to finish it, maybe less.
Also included in the dlc are the N7 Valkyrie assault rifle and a couple of weapon mods from MP, and after finishing it you get to use Lash and Flare.

I really hope flare makes it into mp, together with Aria's "biotic boss" passive tree.
