So for anyone who has beaten both campaigns (probably everyone) too short.... anyways, you might have noticed that it changes the ending movies, instead it zooms out from the burning arc, and it shows a cruise ship approaching the arc....Last I heard, there wasnt a moving plane or boat for 20 or so years. Also you hear in the security side of the mission for the airport, that there is an outside world, but in worse shape than the arc and that when contact was made, they tried to find the arc's location by torturing two men. So my theory is that the resistance plane with that Nachiev (bad spelling) guy flying might have found people who are in pursuit of the arc. Or they were already on their way to the arc. Any comments? am i just delusional? or please tell me this means there is more to the story than just 8 lvls! still, those 8 lvls are fun...
