Descent to Core is the fifteenth map of Speed of Doom. It was designed by Josh Sealy and uses Wash, an original track by Stuart Rynn. The par time is unknown.


The start




  1. The first secret is just past the stairs that go up the blue door. Jump, not in the moat but on the catwalk to get a soulsphere.
  2. You see the second one up behind bars where the spider mastermind is. You need to arch-jump on the small grass thing with a health bonus. Get the red key and another soulsphere.
  3. The last one is down right of the end switch. Open the red door.
