10 Secret Areas That Exist In Your Favourite Video Games

9. Batman: Arkham Asylum - Quincy Sharp's Secret Room

There's a good chance that even among players that completed Arkham Asylum to a 100% rating, this secret area will be a surprise. Warden Sharp's hidden room could be found right from his office, and yet it's one of the best-kept secrets in modern gaming.

In order to access the secret room, players had to blast it open using explosive foam. The twist is that the wall wouldn't be highlighted using Batman's detective vision, it didn't appear on maps, and it required three applications of the foam, blown simultaneously in order to find. Within the secret room lies blueprints for 'Arkham City,' an explicit teaser for the next game in the series.

Nobody reported finding the room for over half a year, and Rocksteady team eventually decided to announce it on their 'Game of the Year' podcast.
