campaign was very "k... wait what?" the ending confused me as well. It struck as me as A) half-ass, B) gonna be a sequel? C) story-DLC? seriously it was one half-cocked ending. Not to mention the reason FOR the conflict doesn't make any sense. We don't even know Soloman's motive for his 'revenge'. just yeah.. garbage story. some really fun set pieces, but no story there. just set pieces strung together. Maybe i ask for too much, but for once i'd like a modern shooter with gameplay like Battlefield to have a campaign that makes some damn sense to the viewer.
SPOILER ALERT- THOSE WHO HAVE NOT FINISHED BATTLEFIELD 3, DO NOT READ
So... that was a pretty bad campaign. So bad that halfway through, about a month ago, I stopped playing it altogether (the online mode kept me hooked, though). However, yesterday, I continued the campaign, and, well, the ending was... rushed, confused, and made no sense.
I liked the car chase, but I wanted it to be a bit longer. Also, I expected a large scale firefight, but the last mission was, in fact, the easiest in the entire game. The game didn't follow up on what happened to Black (did he die? Did his name get cleared? Was the nuke diffused successfully?) and the last cutscene was a mess. Who knocked on the door, and why did Dima ready his gun when he heard the knock? I'm not sure I understand.
It might be just me, but I felt the ending was rushed and confusing. They needed to elaborate on a lot of stuff, something they did not do.
That said, a few missions of the campaign were really enjoyable, like Kaffarov and Operation Swordbreaker. It was a bit too linear, though, even more linear than Modern Warfare 3 (I loved MW3's campaign).
However, the online is the real star here for me, and BF3 is still one of the best games I've played all year, despite the lackluster campaign.
