Secrets

 * 1) Just east of where the red key is, open the brown wall to get the yellow key. (sector 170)
 * 2) Inside the yellow key building, open the wall with the poison sign on it to find a partial invisibility. (sector 177)
 * 3) Use the switch just north from where the yellow key is located, then go onto the ridge that dropped. Quickly run back north and east down the steps and towards the closed-off alley in the northeast, where there will be a lowered lift. Ride it up to appear in a yard around the soul sphere. To reach it, there is a switch on one of the pillars, which lowers another nearby ridge and the soul sphere pillar. (sector 224)
 * 4) From the platform with three gardens, you can jump southwest to the window with a megaarmor. (sector 269)
