We all have shadows of darkness deep inside. And some of us also have decaying rat corpses.

The Exploring Your Inner Dungeons Challenge was a challenge for the games Monsters' Den: Book of Dread that was released on June 5th, 2008 and lasted until June 12th, 2008. To complete it, the player had to get a score of 5,000 points, which was equivalent to fully clearing 2 floors without dying on the standard difficulty setting with no modifiers. The player could choose to make the game harder or easier to score points faster or slower, respectively. Completing the challenge would give the player the Replay 1 version of the Scroll of Inner Focus card.
