You'll beat the campaign in 4 uneventful missions... In that time you only get one weapon unique to RoI and its after completing the short campaign. [spoiler]its another -blam!-ing sword... Nothing new about it...[/spoiler]The change in theme for the cosmodrome is boring and doesn't change the fact that everything is still the same there... With some added fissures and cuts into rock faces. If you've watched a single teaser trailer, you've probably experienced the ENTIRE storyline within a few minutes... There are additional missions after completing the campaign and the quest lines seem to add more grinding time, but the fact that I felt bored the entire time I was playing left me uninterested in them. If you're buying for the new multiplayer maps and raid then you'll be fine, but it doesn't seem to add much else.
