Secrets

 * 1) In the south-west quarter on the map, which contains three similar and connected rooms with purple waterfalls which create a pool with a column in the centre, the waterfall in the medium height level room (in the north-east room) can be passed through and contains a teleporter to a zone with a backpack, megaarmor, soul sphere, a lot of ammo, and a big trap. (sector 1260)
 * 2) In the secret zone accessed in secret #1, a small passage can be found in the southernmost part, beyond the damaging purple floor, containing an invulnerability. (sector 508)
 * 3) At the beginning of the building in the north-eastern part of the map where the plasma gun can be found, a damaged wall can be found with some bricks in the floor. Go through the hole in the wall by climbing the bricks to grab an armor. (sector 905)
 * 4) In the cavernous section which leads to the area of the final fight (big circular black hole), the computer area map can be easily spotted. Immediately before is a very big and deep hole with highly damaging lava at the bottom. There is a small entrance along this hole you can drop to (hint: the floor of the entrance can be seen without dropping down with proper positioning and high gamma correction levels) to access a secret area where you can grab the computer area map. (sector 746)
 * 5) In the final area of the level past the zone of the final fight, an invulnerability can be easily spotted, but the door to access it is locked. Press on the wall directly opposite the locked door to lower it and access a series of passages, where both a switch and a soul sphere can be found. Pressing the switch will unlock the door to the secret area with the invulnerability. The invulnerability stands on a teleporter to the area of the final fight. (sector 887)
