In a video interview with Xbox.com's Major Nelson, Microsoft's Vice President of Global Marketing Jeff Bell just might have let one of Halo 3's long rumored secrets slip. Towards the end of the interview, while talking about his gaming habits, Bell said that he loved playing Halo 2 co-op with his son and then said that "we'rereally looking forward to playing with my three sons, all together on Halo 3". All together playing Halo 3 eh? Sounds a lot like a four player campaign co-op Halo 3 experience to us. But, to be fair, he didn't specify how he and his children were going to play Halo 3, although his remarks came right after he was talking about the teamwork he and his one son experienced while playing Halo 2 co-op. So, it's not "officially" confirmed, but darned if it doesn't make for some great water cooler material.
