Secrets

 * 1) At the start of the level, open the lightning bolt panel in the northeast corner to find a box of bullets and a backpack. (sector 373)
 * 2) At the entrance into the room with the red skull key, a portion of the stone wall at the south is covered in moss.  Open it to find a chainsaw and a partial invisibility. (sector 701)

Bugs
In the red key area, three linedefs trigger bars to block the exit, while the switch to remove the bars can only be activated once. Re-triggering the bars after the switch has been pressed leaves the player stuck.
