Secret Levels
Omega Outpost: Omega Outpost is accessed from level 3. At the end of the level, just before the exit with the Hell Knights are four switches which operate four columns. To lower the columns properly, use this sequence (#1 being the closest switch to the staircase you just came up, #4 the farthest): 3-1-2-4
Enter the teleporter in the room to the right of the Hell Knights and run across the columns. This will take you to the secret exit
to level 29. On this level you can find the hidden eighth weapon.

Hectic
To warp to Hectic, go to the staging area and destroy all the barrels but the one at the begining, save it for last. Once you have
destroyed the other barrels teleport to the begining, and blast it, now run as fast as you can to the door behind you, open and
and run to the left where there should be a teleporter, just enter it and you're there!

The Lair
Make your way to level 12. Don't jump from the platform the Soulsphere is on just yet. Take a look at the map and you'll
discover that platform you're standing on is shaped like an arrow. Back up and then run into the wall in the direction the arrow
points. This will take you to a secret exit that takes you to The Lair.
