Secrets

 * 1) Sector 73: Find your way to the start room of the original level. The secret room is still there.
 * 2) Sector 1375: Near the green door, go down the corridor with the rotating fans. One of the walls on the right opens. A berserk pack is found inside.
 * 3) Sector 2583: In the room with the giant UAC logo on the floor, jump on the box next to the barrel. Then jump onto the large crate structure, and drop down onto the backpack.
 * 4) Sector 4577: After the underground remotely opened door, in the slime room with bridges, a curved wall with misaligned texture, before crossing the bridges, can be opened. A radiation suit is inside.
 * 5) Sector 4911: In the same area, head east while submerged. There is an alcove containing a super shotgun.
 * 6) Sector 5643: In the room after the yellow door, the wall by the two dead marines can be opened, leading to a "DOPEFISH LIVES!" Easter egg and a megasphere.
 * 7) Sector 5822: In the room with the mega-armour in a elevated position, riding the lift up to get it will open a wall in the corridor to the west. Some health and ammo can be found inside as well as the letters "NMN" referring to Pawel Zarczynski, a member of the KDiZD team, and primary mapper of this level.
