Myth 2 Game
To get to the second secret level you must get to level 20: A Murder of Crows. Go thru the level as you normally would, except after The Deciever has beaten SoulBlighter don't follow him to the exit. Instead exit out of the upper-right corner of the map. You'll then go to the secret level "Limbs, Heads, and Smoking Craters". Have fun blowing stuff up!
