Secrets

 * 1) At the bridge over lava in the caves west of the starting point, there is an opening in the lava to the north. Enter this opening and use the teleporter to appear on top of a frozen waterfall where you can get a megaarmor. (sector 419)
 * 2) In the cavern north of the start, follow the frozen waterfall to a soul sphere. (sector 525)
 * 3) Past the blue bars, drop into the lava on your right to find a platform with boxes of rockets. (sector 826)
 * 4) Just before the large arena near where the exit is, go around the north silo to find a tucked-away teleporter. You will find an invulnerability up here. (sector 1291)
 * 5) South of the blue key, there is a small tunnel you can go into to get a BFG9000. (sector 1346)
