First off I'd like to say that I was a skeptic before playing the beta but now can't wait until the full version releases. The game is a lot of fun and I'm waiting for the maintenance to end so I can go back online again. The one thing that I've found is that it was very easy to get distracted looking for loot at the end of a story mission and I would not be paying attention to any plot points that my ghost was explaining to me. It was maybe after the third play through of the last story mission activating the array before I heard something about an a.i maybe controlling a secret defense system possibly. I mentioned this to my brother and some friends and they couldn't remember these details. As the game is so fun, with the full version it would be easy for players to keep moving on to the next mission but the story told outside of cut scenes could be lost. I went to these control panels and defended them against waves but the why could sometimes be lost.
