You wretch as a strange acrid odor assaults you.

Death and Demon carcass!

No nightmare could have prepared you for this.

You realize that this place was not meant for living humans.

The Demon Key

After you hit the yellow key switch and walk past the arch on your way to the exit, you will hear an earthquake and see the screen shake. Now go all the way back to where the Demon Key is.

A new switch has arisen here. Hit the switch, then run all the way back to where you found the blue key. The little square the blue key was resting on has risen a bit, allowing you to run up into the "tunnel" where the Demon Key now awaits you.

On occasion, the artifact will sometimes disappear before you grab it in the tunnel. Should this happen, you have to run all the way back to its original spot, hit the switch, and head back to the tunnel to pick it up.


There are no secrets in this level.
