It wasn't the best thing ever, but it was decent and held my interest. It was also nice to have something to explain where the next game will start.
I was a little nervous about it considering its a solo mission and I'm not the best with a controller gun, but I surprised myself. I actually killed everyone in the room with the reaper artifact (because I thought you had to) and got the trophy for it. I was a gruesome (for my standards) fight because those assholes were out flanking me left and right. I also liked that they explained why earth would be the first to be invaded considering it's the closest system to the "alpha" relay.
