I think the best was finally taking off to the Moon. It was exciting to travel to space, enter the 'atmosphere', and enjoy the mission while it lasted. Definitely worth my time doing so. My worst is when we were seconds away from defeating the Devil Walker on the Strike Mission, and my only teammate was down. I went to go to revive them, and suddenly the tank took me out. We had to restart the entire thing, which generally made the both of us pretty upset. Overall, the Beta was an amazing experience!
