I think it's great fun. I mean, I get to play as either a Krogan who smashes everything and a bit more that looks at him funny or as a Quarian with a sniper rifle that weighs nearly as much as she does. What's there not to love?
My only complaint is the amount of maps that are currently available. They tend to get old quickly, some new ones might be nice.
I have to say, Cerberus is the easiest enemy to face. They just happen to have the most humanoid build, making them very vulnerable to Bullet-in-the-face syndrome.
So, when will the Elcor Infiltrator and Volus Vanguard DLC be released?
