When I first played RE6, I played as Leon in his campaign and was blown away. There were zombies, good AI, and an interesting story that intertwined with the other characters from other playable campaigns. After finishing Leon's campaign I went onto Chris' and was dissapionted to find no zombies, and the same with Jake's, but aside from that fact, there were great boss fights and again great stories that really caught my attention. The only few things about this game that I had actual problems with, aside from no zombies, was clunky movement controls and a lack of creativity in boss fights. With the movement thing, I was almost contantly getting stuck on enviromental objects. With boss fight creativity you would need a diversity of enemy types and it just wasn't there in RE6. Aside from that, RE6 was a great game with awesome Co-op and was a pretty fun game in my opinion, and if you complete all three campaigns you get a special bonus that is definately worth getting. Now onto the online portion of this game. You can enter other people online game either to help them or do the exact opposite. By helping them of course that means that you would take place as their AI or, there is a new mode called manhunt were you take place as one the protagonist's enemies and try to kill them. Also, the beloved Mercenaries mode is back in which you have certain amount of time to kill as many enemies as you can which earns you points, which can be displayed on a leader board with all your friends. So in my overall opinion of this game, I really enjoyed it and would recommend it to anyone who is interested.
