Yeah, the clock puzzle required some brain effort you don't usually see in RE games, but it was solvable. The first time I did it by myself (offline) I paused the game and wrote on a piece of paper so I wouldn't forget the numbers I had come up with. Usually when you go online, you don't have to do puzzles like that, because someone always knew all the answers anyway.
The Hive B2 puzzle stumped me and my friends so bad that they quit playing the game. None of us knew what the hell "Carmine" was, and it wasn't until I discovered that the ugly-ass symbol in the file was a plus symbol (looked more like a cross) that I had a good idea on what it was telling me to do. Good puzzle, dumb execution.

Actually its the hardest puzzle in both Outbreak games in my opinion followed by the Flashback VH key. I was kind of arrogant, as I taught I was the man in the game. I came crawling for help to people to find out this puzzle. No one responded, I went to the last person I taught I would never go because I dislike this person. And it soo happens to be, that he helped me even more then I taught. I find videos (only on Outbreak) Inferior to understand the puzzles. I need a straight answer. I dont go for gamefaqs, but I rather message people for help. Thats my motto.
